DESCRIPTION  
The DRV8834 provides a flexible motor driver solution for toys, printers, cameras, and other mechatronic  
applications. The device has two H-bridge drivers, and is intended to drive a bipolar stepper motor or two DC  
motors.  
The output driver block of each H-bridge consists of N-channel power MOSFET’s configured as an H-bridge to  
drive the motor windings. Each H-bridge includes circuitry to regulate or limit the winding current.  
With proper PCB design, each H-bridge of the DRV8834 is capable of driving up to 1.5-A RMS (or DC)  
continuously, at 25°C with a VM supply of 5 V. It can support peak currents of up to 2.2 A per bridge. Current  
capability is reduced slightly at lower VM voltages.  
Internal shutdown functions with a fault output pin are provided for over current protection, short circuit  
protection, under voltage lockout and overtemperature. A low-power sleep mode is also provided.  
The DRV8834 is packaged in a 24-pin HTSSOP or VQFN package with PowerPAD™ (Eco-friendly: RoHS & no  
Sb/Br).
