The 17517 is a monolithic triple totem-pole-output power IC designed to be used in portable electronic applications to control small DC motors and solenoids. The 17517 can operate efficiently with supply voltages as low as 2.0 V to as high as 6.8 V. Its low RDS(ON) totem-pole output MOSFETs (0.46 Ω typical) can provide continuous drive currents of 1.0 A and handle peak currents up to 3.0 A. It is easily interfaced to low-cost MCUs via parallel 3.0 V- or 5.0 V-compatible logic. The device can be pulse width modulated (PWM-ed) at up to 200 kHz.
