This document from MOTOROLA Semiconductor provides information on a new product, the 17517 dual motor driver IC, which is designed for controlling small DC motors and solenoids in portable electronic applications. The IC can operate efficiently with low voltage and is easily interfaced with low-cost MCUs via parallel logic. It supports two-motor operation or motor plus solenoid operation with synchronous rectification.
The MPC17517 is a monolithic triple totem-pole-output power IC designed to control small DC motors and solenoids in portable electronic applications. It operates efficiently with supply voltages ranging from 2.0 V to 6.8 V and features low Rds(on) totem-pole output MOSFETs capable of providing continuous drive currents of 1.0 A and handling peak currents up to 3.0 A.
The device supports two-motor operation or motor plus solenoid operation and includes an integrated charge pump and level shifter for gate drive voltages. It also features integrated shoot-through current protection, undervoltage detection, and shutdown circuitry, making it easily interfaced to low-cost MCUs via parallel 3.0 V- or 5.0 V-compatible logic.
| Motor Supply Voltage | 2.0 V to 6.8 V |
|---|---|
| Output Current (Continuous) | 1.0 A |
