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 common-
mode 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
have enough bandwidth, the phase monitoring
sample and hold amplifiers can hold phase
information until the MCU is ready to process it. The
interfaces include SPI and CAN. The pre-driver and
other internal settings can be configured through the
SPI. The CAN is used to communicate with other
electronic control units (ECUs).
