17510

Freescale Semiconductor Advance Information Document Number: MPC17510 Rev. 3.0, 1/2007 1.2 A 15 V H-Bridge Motor Driver IC The 17510 is a monolithic H-Bridge designed to be used in portable electronic applications such as digital and SLR cameras to control small DC motors. The 17510 can operate efficiently with supply voltages as low as 2.0 V to as high as 15 V. Its low RDS(ON) H-Bridge output MOSFETs (0.45 Ω typical) can provide continuous motor drive currents of 1.2 A and handle peak currents up to 3.8 A. It is easily interfaced to lowcost MCUs via parallel 5.0 V compatible logic. The device can be pulse width modulated (PWM-ed) at up to 200 kHz. This device contains an integrated charge pump and level shifter (for gate drive voltages), integrated shoot-through current protection (cross-conduction suppression logic and timing), and undervoltage detection and shutdown circuitry. The 17510 has four operating modes: Forward, Reverse, Brake, and Tri-Stated (High Impedance).
