Description

The TLE94112EL is a protected twelve-fold half-bridge driver designed especially for automotive motion

control applications such as Heating, Ventilation and Air Conditioning (HVAC) flap DC motor control. It is part

of a larger family offering half-bridge drivers from three outputs to twelve outputs with direct interface or SPI

interface.

The half bridge drivers are designed to drive DC motor loads in sequential or parallel operation. Operation

modes forward (cw), reverse (ccw), brake and high impedance are controlled from a 16-bit SPI interface. It

offers diagnosis features such as short circuit, open load, power supply failure and overtemperature

detection. In combination with its low quiescent current, this device is attractive among others for automotive

applications. The small fine pitch exposed pad package, PG-SSOP-24, provides good thermal performance

and reduces PCB-board space and costs.
