ATA6823C Overview
The Atmel® ATA6823C is designed for automotive body and powertrain applications. The IC is used to drive a continuous current motor in a full H-bridge configuration. An external microcontroller controls the driving function of the IC by providing a PWM signal and a direction signal and allows the use of the IC in a motor-control application.
ATA6823C Key Features
- PWM and direction-controlled driving of four externally-powered NMOS transistors
- A programmable dead time is included to avoid peak currents within the H-bridge
- Integrated charge pump to provide gate voltages for high-side drivers and to supply
- 5V/3.3V regulator and current limitation function
- Reset derived from 5V/3.3V regulator output voltage
- Sleep mode with supply current of typically < 45µA, wake-up by signal on pins EN2
- A programmable window watchdog
- Battery overvoltage protection and battery undervoltage management
- Overtemperature warning and protection (shutdown)
- LIN 2.1 pliant
