Product Description

The DRV8834RGET is a Low Voltage Stepper with 32-step indexer or dual brushed DC motor driver (indexer or PH/EN ctrl). It is designed 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 MOSFETs 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 can driving up to 1.5A RMS (or DC) continuously, at 25°C with a VM supply of 5V. The device can support peak currents of up to 2.2A per bridge. Current capability is reduced slightly at lower VM voltages. Internal shutdown functions with a fault output pin are provided for overcurrent protection, short-circuit protection, under-voltage lockout and over-temperature. A low-power sleep mode is also provided.
Built-in indexer logic with simple step/direction control and up to 1/32-step microstepping
Phase/enable control, with the ability to drive external references for >1/32-step microstepping
Dynamic tBLANK and mixed decay modes for smooth microstepping
PWM winding current regulation and limiting
305mR HS + LS (at VM=5V, 25°C) Low RDS(ON)
