Automotive & Control
Dual Triple DMOS Output Drivers with Serial Input and PWM Control
T6819, ATA6829, ATA6831
The T6819/ATA6829/ATA6831 are fully protected driver interfaces designed in smart power BCDMOS tech- nology. They are used to control different loads by a microcontroller in automotive and industrial applications. Each driver of the T6819/ATA6829 is freely configurable and can be PWM controlled separately from a standard serial data interface. The power stages of the ATA6831 are combined to 3 half bridges. Due to the ATA6831’s enhanced PWM signal of up to 25 kHz, the DC motor control is carried out without any audible noise caused by the PWM signal. All kinds of loads such as bulbs, resistors, and inductors can be combined.
