Analog Products Fact Sheet Power Actuation MPC17C724 Dual H-Bridge Motor Driver 0.4 A Dual H-Bridge Motor Driver IC DESCRIPTION MPC17C724FS SIMPLIFIED APPLICATION DI- The MPC17C724FS is a compact monolithic dual channel H-Bridge power IC, ideal for portable electronic applications containing bipolar stepper motors or brush DC motors such as those used in camera lenses and irises. 3.0 V The MPC17C724FS can operate efficiently with supply voltages from 2.7 V to 5.5 V and can provide continuous motor drive currents of 0.4 A with low RDS(ON) of 1.0 Ω. It is easily interfaced to low-cost MCUs via parallel 3.0 Vor 5.0 V-compatible logic and has built-in shoot-through current protection circuit and undervoltage detector to avoid malfunction. The MPC17C724FS has four output control modes: Forward, Reverse, Brake, and TriState (High Impedance). The H-bridge outputs are designed to be independently PWM’ed at up to 200 kHz for speed/torque and current control. 17C724 VDD VM OUT1A OUT1B MCU IN1A OUT2A IN1B IN2A OUT2B PSAVE GND PERFORMANCE • Camera Lens and Irises Outputs • Micro Toy Motor Drive Supply Voltage (VM) • Security Camera Bipolar Step Motor IN2B APPLICATIONS • Web Camera S N ESD (HBM) TYPICAL VALUES 4 3.3 V ± 2000 V Operating Temperature -20°C ≤ TA ≤ 85°C Junction Temperature -20°C ≤ TJ ≤ 150°C FEATURES QUESTIONS • Manufactured in SMOS7 Process Technology • Are you looking for a small motor driver IC for stepper motors? • Built-In 2-Channel H-Bridge Driver • Provides 4 Driving Modes (Forward, Reverse, Break, High Impedance) • Direct Interface to MCU • Do you need a small motor driver IC for one channel 400 mA DC output current? • Low ON-Resistance, RDS(ON) = 1.0 Ω (Typical) • Do you need to reduce the PCB area? • Dual Channel Parallel Drive, RDS(ON) = 0.5 Ω (Typical) • Do you need shoot through current protection? • Output Current Driver (IDR) is 400 mA (Continuous) • Low Power Consumption • Built-In Shoot-Through Current Prevention Circuit • Built-In Low-Voltage Shutdown Circuit • PWM Control Frequency 200 kHz (Max) • Very Compact Size, Comes in 16-Terminal QFN Package (3 x 3 mm Terminal Pitch: 0.5 mm) • Pb-Free Packaging Designated by Suffix Code EP • Devices available for comparison are in the Analog Product Selector Guide - SG1002, and Automotive Product Selector Guide - SG187.
