TPD2005F
TOSHIBA Intelligent Power Device Silicon Monolithic Power MOS Integrated Circuit
TPD2005F
Low-Side Power Switch Array (8 Channels) for Motors, Solenoids, and Lamp Drivers
The TPD2005F is an 8-channel high-side switch array for vertical power MOS FET output. A monolithic power IC, it can directly drive a power load from a CMOS or TTL logic circuit (such as an MPU). It offers overcurrent and overtemperature protection functions.
Features
A high-side switch array incorporating an N-channel power MOS FET (1.2 max.) and an 8-channel charge pump Can directly drive a power load from a microprocessor. Built-in protection against thermal shutdown protection and overcurrent protection 8-channel access enables space-saving design High operating voltage Low on resistance Low operating current : 40 V : 1.2 max. (@VDD = 12 V, IO = 0.5 A (per channel)) : 5 mA max. (@VDD = 40 V, VIN = 0 V) Weight: 0.29g (typ.)
Supports parallel operation. Supplied in an SSOP-24 package (300 mil) in embossed taping.

Timing Chart
Note:
The overheating detector circuits feature hysteresis. After overheating is detected, normal operation is restored only when the junction temperature falls by the hysteresis amount (10C typ.) in relation to the overheating detection temperature.

Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook ("Handling Precautions"/Derating Concept and Methods) and individual reliability data (i.e. reliability test report and estimated failure rate, etc).

Description of Protector Circuit
(1) Overtemperature Protection There are four built-in overheating detector circuits, one each for channels 1 and 2; channels 3 and 4; channels 5 and 6; and channels 7 and 8, respectively. The circuit logic is such that, when any of the four detectors detects overheating, the circuit turns off the output of both its channels(for example, both channels 1 and 2). The overheating detector circuits feature hysteresis. After overheating is detected, normal operation is restored only when the junction temperature falls by the hysteresis amount (10C typ.) in relation to the overheating detection temperature. (2) Overcurrent Protection When overcurrent is detected, the overcurrent limiter function limits the output current. Normal operation is restored when the load current drops below the overcurrent detection value.

Caution on Usage
1. As protection against reverse connection of batteries is not provided, take protective measures using external circuits. 2. As a negative bias protector circuit is not built into the output pins, if negative bias is applied to the output pins, be sure to connect a freewheel diode between OUT and GND.
Moisture-Proof Packing
After the pack is opened, use the devices in a 30C, 60% RH environment, and within 48 hours. Embossed-tape packing cannot be baked. Devices so packed must be within their allowable time limits after unpacking, as specified on the packing. Standard tape packing quantity: 2000 devices / reel (EL1)
