DESCRIPTION/ORDERING INFORMATION
Designed to control dc motors by using pulse width modulation(PWM),the DRV8800/DRV8801is capable of peak output currents up to±2.8A and operating voltages up to36V.
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/DRV8801is supplied in a thin-profile16-pin QFN(RTY)PowerPAD™package,providing enhanced thermal dissipation.The devices are lead free(Pb free).
