5A Brushed DC or Half-Bipolar Stepper Motor Driver (PWM Ctrl)

5A Brushed DC or Half-Bipolar Stepper Motor Driver (PWM Ctrl) - DRV8842


The DRV8842 provides an integrated motor driver solution for printers, scanners, and other automated equipment applications. The device has one H-bridge driver, and is intended to drive one DC motor, one coil of a stepper motor, or other loads. The output driver block consists of N-channel power MOSFETs configured as an H-bridge. The DRV8842 can supply up to 5-A peak or 3.5-A RMS output current (with proper heatsinking at 24 V and 25°C).

Separate inputs to independently control each half of the H-bridge are provided.

Internal shutdown functions are provided for overcurrent protection, short-circuit protection, undervoltage lockout, and overtemperature.

TheDRV8842 is available in a 28-pin HTSSOP package with PowerPAD (Eco-friendly: RoHS & no Sb/Br).

For all available packages, see the orderable addendum at the end of the datasheet.
