>70mA with external boost transistor
Adjustable watchdog and reset generation
Smart wake-up via BUS interface or KL15
High side charge pump driver
Self-controlled dead time generation
Motor current measurement amplifier
Over current switch-off (dynamical change)

AEC-Q100 Qualification Applications This IC is developed for automotive applications BLDC (EC) motor control, multiple DC motor con The IC ensures a safe, autonomous start-up and
wake-up. It is suitable for high temperature applications. An integrated linear regulator supplies an
external microcontroller. The supply output current
can be "boosted" with an external transistor.
For controlling the motor, six power FET gate drivers
with automated dead time generation are implemented.
