Texas Instruments Motor Driver DRV8837CDSGR Low-Voltage H-Bridge Driver
The DRV8837CDSGR is a compact, low-voltage H-bridge motor driver designed for driving small DC motors and other inductive loads. It features low MOSFET on-resistance (HS + LS 1 Ω) and can handle up to 1 A of continuous current. The device operates over a wide supply voltage range of 0 V to 11 V for the motor power supply (VM) and 1.8 V to 7 V for the logic power supply (VCC). This makes it ideal for applications such as cameras, toys, and low-voltage, battery-powered devices.
DRV8837CDSGRFeatures
The DRV8837CDSGR includes several key features to enhance its performance and reliability. It has a standard PWM interface for speed control and direction selection. Additionally, the chip incorporates various protection mechanisms, including overcurrent protection (OCP), thermal shutdown (TSD), and undervoltage lockout (UVLO) for the logic supply (VCC). The device also features a low-power sleep mode with a maximum sleep current of 120 nA, controlled via the nSLEEP pin. Its small 8-WSON package with an exposed pad (2.0 × 2.0 mm) ensures efficient thermal performance.
