SLVSBJ4B – OCTOBER 2012 – REVISED JULY 2016 DRV3202-Q1 3-Phase Brushless Motor Driver
Not Recommended for New Designs 1 Features 3 Description The DRV3202-Q1 device is a field effect transistor
(FET) pre-driver designed for 3-phase motor control
and its application such as an oil pump or a water
pump. It is equipped with three high-side pre-FET
drivers and three low-side drivers which are
controlled by an external microcontroller (MCU). The
power for the high side is supplied by a charge pump
and no bootstrap cap is needed. For commutation,
this integrated circuit (IC) sends a conditional motor
drive signal and output to the MCU. Diagnostics
provide undervoltage, overvoltage, overcurrent,
overtemperature and power bridge faults. The motor
current can be measured using an integrated current
sense amplifier and comparator in a battery commonmode range, which allows the motor current to be
used in a high-side current sense application. Gain is
attained by external resistors. If the MCU does not …
