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 lowwawd.DastaSsheuetc4Uh.comas 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.

Function
Temperature prewarning: high = warning
Normal operation: high = output is on, low = output is off
Open-load detection: high = open load, low = no open load
(correct load condition is detected if the corresponding output is
switched off); not affected by SRR

Over-load detected: set high, when at least one output is
switched off by a short-circuit condition or an overtemperature
event. Bits 1 to 6 can be used to detect the affected switch.
(open-load detection bit OLD = high)
Inhibit: this bit is controlled by software (bit SI in input register)
High = standby, low = normal operation
Power-supply fail: undervoltage at Pin VS detected
