RS8837 RS8837 Low-Voltage H-Bridge Driver 1 FEATURES 3 DESCRIPTIONS • H-Bridge Motor Driver - DC Motor or Other Loads - Low On-Resistance: HS+LS 320mΩ • 1.8A Maximum Drive Current • Separate Motor and Logic Supply Pins: - Motor VM: 0 to 12V - Logic VCC: 2.5V to 7V • Low-Power Sleep Mode With 36nA TYP Sleep Current • VCC Under-Voltage Lockout • Over-Current Protection • Thermal Shutdown Protection • Lead-Free Packages: DFN2x2-8L, SOIC-8 The RS8837 is an integrated H-bridge driver designed for dc motors and coils bi-directional turning. Usually used for small current driving, such as camera, smart locks, toys, smart sweeper, electromagnetic valve, and other low-voltage or battery-powered motion control applications. The RS8837 can drive one DC motor or other devices like solenoids, supply up to 1.8A maximum output current. The output driver block consists of N-channel power MOSFET configured as an H-bridge to drive the motor winding. An internal charge pump generates needed gate drive voltages. The RS8837 operates on a motor power supply voltage from 0 to 12V, and a device power supply voltage of 2.5V to 7V. Also provide internal shutdown functions for over-current protection, short-circuit protection, undervoltage lockout and over-temperature. 2 APPLICATIONS • DSLR Lenses • Cameras • Robotics • Consumer Products, such as Toys, Smart Locks • Device Information (1) PART NUMBER Medical Devices RS8837 DFN2x2-8L(8) BODY SIZE (NOM) 2.00mm×2.00mm SOIC-8(SOP8) 4.90mm×3.90mm PACKAGE (1) For all available packages, see the orderable addendum at the end of the data sheet. 4 Typical Application Circuit 2.5V to 7V VCC 0 V to 12 V VM PWM or PH and EN nSLEEP REV A.1 RS8837 Brushed DC Motor Driver 1 / 18 1.8 A M www.run-ic.com  PDF
