1.3 Description
The DRV91690 is an highly integrated programmable motor controller that provides 3-phase gate drivers,
16-bit processing core, PWM generation, 10-bit ADC, voltage regulators needed for three phase brush-
less DC motor applications.
The DRV91690 provides three half bridge pre-drivers, each capable of driving a high side and a low side
external N-type MOSFETs. The device uses a boot strap architecture for the gate drivers with built-in
trickle charge pump to support 100% duty cycle. The 12-V programmable LDO generates the drive
voltage (Vgs in the range of 8 V-12 V) for the MOSFETS.
The programmable gain Differential Shunt Amplifier (DSA) is used for accurate phase current
measurements that support bi-directional current sensing. It also give the user the ability to monitor phase
currents for OC conditions with an accurate reference set by a 10-bit DAC .
The processor subsystem includes 16-bit RISC MSP430F5xxx series core with 32-bit multiplier as a
peripheral, Spy-By-Wire debug interface and in-system programmable 32-kB Flash and 2-kB SRAM.
The DRV91690 operates from a single supply with the range of 8V-35V. The device has on-chip 3.3-V and
7-V regulators and can provide load current of 30mA and 10mA respectively to bias external circuits or
sensors such as hall sensors.

The Device provides detailed fault reporting of the built-in protection for over-voltage, over-current,
undervoltage lockouts and low side VDS monitoring schemes.
On chip peripherals include PWM Controller, Universal Serial Communication Interface (USCI) that can
handle either UART or SPI protocol, five 16-bit general purpose timers that support external
capture/compare in addition to 32-bit Watchdog timer unit.
The device supports back-emf comparators or external hall input based standard Trapezoidal Control and
attenuated phase voltages are routed to ADC for implementing advanced motor control algorithms.
The DRV91690 is assembled in 0.5mm pitch 48-pin PHP package with PowerPAD™ heat sink.
