DESCRIPTION/ORDERING INFORMATION
Designed to control dc motors by using pulse width modulation (PWM), the DRV8800/DRV8801 is capable of
peak output currents up to ±2.8 A and operating voltages up to 36 V.
The PHASE and ENABLE inputs provide dc motor speed and direction control by applying external pulse-width
modulation (PWM) and control signals. Internal synchronous rectification control circuitry provides lower power
dissipation during PWM operation.
Internal circuit protection includes motor lead short-to-supply/short-to-ground, thermal shutdown with hysteresis,
undervoltage monitoring of VBB and VCP, and crossover-current protection.
The DRV8800/DRV8801 is supplied in a thin-profile 16-pin QFN (RTY) PowerPAD™ package, providing
enhanced thermal dissipation. The devices are lead free (Pb free).
