| (R) VN710SP AUTOMOTIVE GLOW PLUG DRIVER PRELIMINARY DATA TYPE VN710SP s s s s s RDS(on) 18m IOUT 35 A VCC 16 V CMOS COMPATIBLE INPUT ON STATE OPEN LOAD DETECTION OFF STATE OPENLOAD DETECTION SHORTED LOAD PROTECTION UNDERVOLTAGE AND OVERVOLTAGE SHUTDOWN PROTECTION AGAINST LOSS OF GROUND VERY LOW STAND-BY CURRENT WHEN ENABLE PIN IS LOW REVERSE BATTERY PROTECTION (*) 10 1 s s PowerSO-10TM s DESCRIPTION The VN710SP is a monolithic device made using STMicroelectronics VIPower M0-3 technology, intended for driving any kind of load with one side connected to ground. Active VCC pin voltage clamp protects the device against low energy spikes (see ISO7637 transients compatibility table). Active current limitation combined with thermal shutdown protect the device against BLOCK DIAGRAM overload. After a thermal shutdown event, device stays latched off and diagnostic stays at a low level until next falling edge of input signal. The device detects open load condition both in on state and off state. Output shorted to VCC is detected in the off state. Device automatically turns off in case of ground pin disconnection. Enable pin allows to switch the device to idle state with very low quiescent current from VCC. When enable is low, device turns off regardless of input pin state.

This can be used with any type of load. The following is an indication on how to dimension the RGND resistor. 1) RGND 600mV / (IS(on)max). 2) RGND (-VCC) / (-IGND) where -IGND is the DC reverse ground pin current and can be found in the absolute maximum rating section of the of the device's datasheet. Power Dissipation in RGND (when VCC<0: during reverse battery situations) is: PD= (-VCC)2/RGND This resistor can be shared amongst several different HSD. Please note that the value of this resistor should be calculated with formula (1) where IS(on)max becomes the sum of the maximum on-state currents of the different devices. Please note that if the microprocessor ground is not common with the device ground then the RGND will produce a shift (IS(on)max * RGND) in the input thresholds and the status output values. This shift will vary depending on many devices are ON in the case of several high side drivers sharing the same RGND. If the calculated power dissipation leads to a large resistor or several devices have to share the same resistor then the ST suggest to utilize Solution 2 (see below). Solution 2: A diode (DGND) in the ground line. A resistor (RGND=1k) should be inserted in parallel to DGND if the device will be driving an inductive load. This small signal diode can be safely shared amongst several different HSD. Also in this case, the presence of the ground network will produce a shift (j600mV) in the input threshold and the status output values if the microprocessor ground is not common with the device ground. This shift will not vary if more than one HSD shares the same diode/resistor network. LOAD DUMP PROTECTION Dld is necessary (Transil or MOV) if the load dump peak voltage exceeds VCC max DC rating. The same applies if the device will be subject to transients on the VCC line that are greater than the ones shown in the ISO T/R 7637/1 table. C I/Os PROTECTION: If a ground protection network is used and negative transient are present on the VCC line, the control pins will be pulled negative. ST suggests to insert a resistor (Rprot ) in line to prevent the C I/Os pins to latch-up. The value of these resistors is a compromise between the leakage current of C and the current required by the HSD I/Os (Input levels compatibility) with the latch-up limit of C I/Os. -VCCpeak/Ilatchup Rprot (VOHC-VIH-VGND) / IIHmax Calculation example: For VCCpeak= - 100V and Ilatchup 20mA; VOHC 4.5V 5k Rprot 18.57k. Recommended Rprot value is10k. 7/11 1 VN710SP Figure1: Waveforms NORMAL OPERATION INPUT LOAD VOLTAGE STATUS UNDERVOLTAGE VCC VUSD VUSDhyst INPUT LOAD VOLTAGE STATUS undefined OVERVOLTAGE VCC INPUT LOAD VOLTAGE STATUS OPENLOAD INPUT LOAD VOLTAGE STATUS tDOL(on) tDOL(on) VOV VCC OVERTEMPERATURE ENABLE Tj INPUT LOAD CURRENT STATUS TTSD TR SHORT TO VCC INPUT LOAD VOLTAGE STATUS undefined tDOL(off) undefined tDOL(off) 8/11 1 1 VN710SP PowerSO-10TM MECHANICAL DATA DIM.
