Hot-selling and scarce DRV8834PWPR Dual-Bridge Stepper or DC Motor Driver IC HTSSOP24 spot stock

Product Descriptions

The DRV8834 provides a flexible motor  driver solution for  toys,   printers,   cameras,   and other mechatronic applications.  The device has two Hbridge 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 Hbridge 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. 5-A RMS (or  DC) continuously, at 25°C with a V_M supply of 5 V. The device can support peak currents of up to 2.2 A per bridge. Current capability is reduced slightly at lower V_M voltages.

Internal shutdown functions with a fault output pin are provided for   overcurrent   protection,   short-circuit protection,          undervoltage     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) .
