Features
Description
The T6819/T6829 are fully protected driver interfaces designed in 0.8 µm BCDMOS
technology. They are used to control up to six different loads by a microcontroller in
automotive and industrial applications.
Each of the three high-side and three low-side drivers is capable to drive currents up
to 1.5 A. Each driver is freely configurable and can be controlled separately from a
standard serial data interface. Therefore, all kinds of loads such as bulbs, resistors,
capacitors and inductors can be combined. The IC design especially supports the
applications of H-bridges to drive DC motors. The capability to control each output
with an external PWM signal opens additional applications.
Protection is guaranteed regarding short-circuit conditions, overtemperature and und-
ervoltage. Various diagnostic functions and a very low quiescent current in stand-by
mode opens 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.

... Functional Description Serial Interface T6819/T6829 4 Data transfer starts with the falling edge of the CS signal. Data must appear at DI syn- chronized to CLK and are accepted on the falling edge of the CLK signal. LSB (bit 0, SRR) has to be transferred first. Execution of new input data is enabled on the rising edge of the CS signal ...

... OVL bit is not set by an overcurrent. By writing a high to the SRR bit in the input register the OVL bit is reset and the disabled outputs are enabled. The SI bit in the input register has to be set to zero to inhibit the T6819/T6829. All output stages are then turned off but the serial interface stays active. The current consumption is reduced to less than 5 µ ...
