They are used to allow a microcontroller to control up to three different loads in automotive and industrial applications. Each of the three high-side and three low-side drivers is capable of driving currents up to 1.0A. Due to the enhanced PWM signal up to 25kHz it is possible to generate a smooth control of, for example, a DC motor without any noise. The drivers are internally connected to form three half-bridges and can be controlled separately from a standard serial data interface, enabling all kinds of loads, such as bulbs, resistors, capacitors and inductors, to be combined. The IC design especially supports the application of H-bridges to drive DC motors. Protection is guaranteed with respect to short-circuit conditions, overtemperature and undervoltage. Various diagnostic functions and a very low quiescent current in standby mode enable a wide range of applications. Automotive qualification protection against conducted interferences, EMC protection and 2-kV ESD protection gives added value and enhanced quality for exacting requirements of automotive applications.
