SLVSBT3C – MARCH 2013 – REVISED JULY 2016 DRV3204-Q1 Three-Phase Brushless Motor Driver
Not Recommended for New Designs 1 Features 3 Description The DRV3204-Q1 device is a field-effect transistor
(FET) pre-driver designed for three-phase motor
control for applications such as an oil pump or a
water pump. The device has three high-side pre-FET
drivers and three low-side drivers which are under the
control of an external MCU. A charge pump supplies
the power for the high side, and there is no
requirement for a bootstrap capacitor. For
commutation, this integrated circuit (IC) sends a
conditional motor signal and output to the MCU.
Diagnostics provide undervoltage, overvoltage,
overcurrent, overtemperature and power-bridge
faults. One can measure the motor current using an
integrated current-sense amplifier and comparator in
a battery common-mode range, which allows the use
of the motor current in a high-side current-sense …
