TPIC0108B

The TPIC0107B is a PWM control intelligent H-bridge designed specifically for dc motor applications. The device provides forward, reverse, and brake modes of operation. A logic supply voltage of 5 V is internally derived from V_CC.

The TPIC0107B has an extremely low r_DS(on), 280 mW typical, to minimize system power dissipation. The direction control (DIR) and PWM control (PWM) inputs greatly simplify the microcontroller overhead requirement. The PWM input can be driven from a dedicated PWM port while the DIR input is driven as a simple low speed toggle.

The TPIC0107B provides protection against over-voltage, over-current, over-temperature, and cross conduction faults. Fault diagnostics can be obtained by monitoring the STATUS1 and STATUS2 terminals and the two input control lines. STATUS1 is an open-drain output suitable for wired-or connection. STATUS2 is a push-pull output that provides a latched status output. Under-voltage protection ensures that the outputs, OUT1 and OUT2, will be disabled when V_CC is less than the under-voltage detection voltage V_(UVCC).

The TPIC0107B is designed using TI's LinBiCMOSE process. LinBiCMOS allows the integration of low power CMOS structures, precision bipolar cells, and low impedance DMOS transistors.

The TPIC0107B is offered in a 20-pin thermally enhanced small-outline package (DWP) and is characterized for operation over the operating case temperature of 40°C to 125°C.
