The DRV89xx-Q1 is a pin-to-pin compatible family of integrated multi-channel half-bridgedrivers with 4 to 12 half-bridges. The device family features low on-state resistance(RDS(ON)) which improves thermal performance during high current operation(rms currents up to 1-A).

The device can drive the 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. With its wide voltage range, the device cansupport high fluctuation in battery voltage because of crank-start and load dump conditions.

A standard 16-bit, 5-MHz serial peripheral interface (SPI) with daisy chain capabilityprovides a full-configurability and detailed diagnostics. Internal PWM generators (with PWMfrequency support of 2-kHz) allows PWM control which enables current limiting during motoroperation and LEDs dimming control. The device has four (12 and 10 channel devices) / eight (8, 6and 4 channel device) PWM generators which are programmable for four different PWM frequencies andindividual 8-bit duty control.

The device supports numerous protection and diagnostic features. Open load detection(OLD) feature allows an easy monitoring of the load connected to the half-bridge. A low current OLDmode allows the detection of very low currents and a passive OLD mode enables the offline OLD. Thedevice is also fully-protected from short-circuit conditions (short to OUTx, supply and ground) andsupport fault monitoring on the nFAULT pin. Moreover, OTW and OTSD ensures the device thermalprotection in scenario of over-heating.
