Atmel has released new driver ICs for brushless DC motor applications. These new devices can also be used for premium-class convenience electronics such as power window or seat adjustment applications, which benefit from the drivers’ low noise. The ATA6833 and ATA6834 integrate watchdog, voltage regulator, and LIN interface functionality.
The 6833 is a BLDC motor driver with 3 half-bridge gate drivers. The three push-pull stages with integrated charge pump can drive six external NMOS transistors. The integrated watchdog monitors the microcontroller, which in turn is supplied by an integrated voltage regulator programmed to 5 V or 3,3 V output voltage providing 100 mA current capability. Current consumption in standby mode is less than 50 μA.
The 6834 handles operating chip temperatures up to 200°C and is therefore suitable for all high-temperature automotive 'under-the-hood' applications where actuators handle the flow of hot exhaust gas or hot oil. To implement space-saving designs, the ECUs can be attached to a turbo charger or used to build a mechatronic unit along with a pump motor.
The ATA6833/34 provide several protection features including a two-stage thermal warning and thermal shut-off as well as open-load, overload, short-circuit, and under-voltage detection with switch-off functionality. To protect the external NMOS transistors, built-in shoot-through protection helps to avoid dangerous simultaneous activation of a high-side and a low-side transistor between supply and ground. Customers can adapt the dead time to the needs of their NMOS transistors by the value of an external resistor/capacitor combination.
