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 Ωmax.) 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 Ωmax. (@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.

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 (10°C 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.

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.
