3 Description
The DRV89xx-Q1 is a pin-to-pin compatible family of
integrated multi-channel half-bridge drivers with 4 to
12 half-bridges. The device family features low on-
state resistance (RDS(ON)) for improved thermal
performance during high-current operation.
These devices can drive brushed-DC (BDC) motors
or stepper motors in independent, sequential, or
parallel mode. The half-bridges are fully controllable
to achieve a forward, reverse, coasting and braking
operation of motor.
These devices feature standard 16-bit, 5-MHz serial
peripheral interface (SPI) with daisy chain capability
for complete configuration and detailed diagnostics.
Depending on the device, four or eight programmable
PWM generators are integrated to allow for current
limiting during motor operation or LED dimming
control.
The device includes numerous protection and
diagnostic features including an nFAULT pin to alert
the system when a fault occurs. The device features
a low-current open load detection (OLD) mode to
detect open-load conditions when the nominal load
current is small and a passive OLD mode for offline
OLD. The device is also fully-protected from short-
circuit, undervoltage, and over-temperature
conditions.
