2. Logic unit for motor driver
Function
This circuit is used to input from the DATA pins micro-step current setting data and to transfer them to the subsequent stage. By switching the SETUP pin, the data in the mixed decay timing table can be rewrite External input data and the 2-bit input signal from 16-bit shift register can be used to set the torque circuit. When 1 is input to one of them, 1 is reflected such as a function of OR gate.

3. Current feedback circuit and current setting circuit for motor driver
Function
The current setting circuit is used to set the reference voltage of the output current using the micro-step current setting data input from the DATA pins. The current feedback circuit is used to output to the output control circuit the relation between the set current value and output current. This is done by comparing the reference voltage output to the current setting circuit with the potential difference generated when current flows through the current sense resistor connected between RS and VM. The chopping waveform generator, to which a capacitor is connected, generates clock (OSC-CLK) used as reference for the chopping frequency, so that these two circuits are pure digital logic.

Note 1: Thermal shutdown (TSD) circuit When the IC junction temperature reaches the specified value and the TSD circuit is activated, the internal reset circuit is activated switching the outputs of both motors to off. When the temperature is set between 130 (min) to 170C (max), the TSD circuit operates. When the TSD circuit is activated, the function data latched at that time are cleared. Output is halted until the reset is released. While the TSD circuit is in operation, the charge pump is halted. Note 2: Overcurrent protection circuit When current exceeding the specified value flows to the DCDC output, the internal reset circuit is activated switching the outputs of both shafts to off. When the ISD circuit is activated, the function data latched at that time are cleared. .com The overcurrent protection circuit remains activated until the VM voltage is reapplied. Activating the ISD initializes all the circuits in the IC, which causes the charge pump to be stopped. For the failsafe operation, insert a fuse in the power supply.

Calculation of Set Current
To obtain the motor setting current value (peak current), values of RRS, Vref and Torque should be determined according to the equation below.
I out (max) = 1 Torque (torque = 100, 75, 50, 25% : input serial data) x Vref (V) x Vref (gain ) R RS ( )
1/Vref (gain): 1/Vref attenuation ratio is 1/4.0 (typ.). For example, to input Vref = 1 V and Torque = 100% and to output Iout = 0.25 A, RRS = 1.0 (0.1 W or more) is required.
Formulas for Calculating Reference Oscillation Frequency (chopping reference
frequency)
The M_osc oscillation frequency (fosc_M) and, chopping frequency (fchop) can be calculated by the following formulas : fosc_M = 1 [Hz] x (CR x 36000R + x C)
KA (constant): 0.523 KB (constant): 600 R = 3.6 k (internal resistor)
fchop = M_osc [Hz] 8
t4U.com
Example: When COSC = 560 pF is connected, M_osc = 813 kHz. At this time, the chopping frequency fchop is: fchop = fosc/8 = 101 kHz. .com Note: fchopc =
1 fosc
DataShee
tosc_M = t (charge) + t (discharge) tosc_M: Motor OSC oscillation cycle t (charge): Motor OSC charge time
DCDC Converter Oscillating Frequency
fDCDC (DCDC PWM frequency) = 50 ()/(0.8 x COSC_D) (Hz) PWM frequency for DCDC block is about 100 kHz when COSC_D is 620 pF. Example: COSC_D = 680 pF: 91 kHz = 620 pF: 100 kHz = 560 pF: 111 kHz = 510 pF: 122 kHz = 470 pF: 133 kHz = 390 pF: 160 kHz

Startup Sequence of Power Supply (Voltage)
(1) When VM supply voltage exceeds VMR voltage, charge pump reset is cleared. (2) When charge pump voltage exceeds the normal voltage (Cp R) and after the DCDC_READY time delayed, 3.3-V (5 V) DC/DC converter reset is cleared, and 3.3-V DCDC goes up. (3) The DC/DC converter operated with soft switching Mode at initial charging up through 90 % of the normal voltage by current controlling. After that, the converter is operated with full-charging Mode. (4) When external signal becomes High, 12-V DCDC starts charging. (12-V DCDC is switched from the soft switching Mode to the full Mode same as the 3.3-V DCDC.)

tONG: Time taken for capacitor Ccp2 (charging capacitor) to fill up Ccp1 (capacitor used to save charge) to VM + VDD after a reset is released. Until the voltage of Ccp1 reaches VM + VDD, the motor and the DCDC converter do not operate normally. To prevent erroneous operations, the TB62205FG incorporates a protection circuit. When the voltage of the charge pump is increased up to the specified level, the motor can operate standalone. However, the initial charging of the DCDC converter starts at this timing. Thus, the DCDC .com converter startup time should be included when the system startup time is set. Basically, the larger the Ccp1 capacitance, the longer the initial charge-up time but the smaller the voltage fluctuation. The smaller the Ccp1 capacitance, the shorter the initial charge-up time but the larger the voltage fluctuation. Depending on the combination of capacitors (especially with small capacitance), voltage may not be sufficiently boosted. Thus, use the capacitors under the capacitor combination conditions (Ccp1 = 0.22 F, Ccp2 = 0.022 F) recommended by Toshiba.

Output stops (RESET mode) CR oscillating (chopping reference waveform) min max
(Non-detection time) ISD BLANK time
min max ISD operating time
When overcurrent starts to flow into the output stage (overcurrent state occurs)
The overcurrent protection circuit has a non-detection time to prevent erroneous detection of spike current generated in diode recovery current (IRR) or at switching. The non-detection time being synchronized with the CR cycle for setting chopping frequency is expressed as follows. Non-detection time = 4 x CR cycle
t4U.com
Time required to stop the output after overcurrent flows into the output stage is expressed as follows. Minimum time = 5 x CR cycle Maximum time = 8 x CR cycle Note that the operating times as shown above are achieved when overcurrent flows as it is expected. Depends on the timing of output control mode, the circuit may not be triggered. Thus, to ensure safe operation, please insert a fuse in the VM power supply. (The capacity of the fuse is determined according to a condition to be used. Please select one whose capacity does not exceed the power dissipation for the IC to avoid any operating problems.)
