Features
* ATA6833 Temperature Range TJ = 150°C
* ATA6834 Extended Temperature Range TJ = 200°C
* Direct Driving of 6 External NMOS Transistors with a Maximum Switching Frequency of
50 kHz
* Integrated Charge Pump to Provide Gate Voltages for High-side Drivers and to Supply
Applications
* In addition, the circuits provide a 3.3V/5V linear regulator and a window watchdog. The circuit includes various control and protection functions like overvoltage and overtemperature protection, short circuit detection, and undervoltage management. Thanks to these function blocks, the driver fulfil
