Product Overview
The DRV8886 is a Texas Instruments Power_Management IC for stepper motor drive applications. Its integrated architecture uses two N-channel power MOSFET H-bridge drivers and supports PWM microstepping from full-step through 1/16 microstepping using a STEP/DIR interface. Integrated current sense eliminates external sense resistors and provides full-scale current accuracy of +/-6.25%. The PWM regulation scheme uses fixed off-time control with slow and mixed decay options.
The driver operates from an 8 to 37 V VM supply, with an absolute maximum VM range of -0.3 to 40 V and a specified VM ramp-rate limit of 0 to 2 V/us. Output ratings include 2 A full-scale current per bridge and 1.4 A RMS current per bridge at 24 V and TA=25°C, dependent on PCB design, with a 3 A per-bridge peak drive current absolute maximum.
Package options are a 24-pin HTSSOP PowerPAD (PWP), 7.80 mm x 4.40 mm, and a 28-pin WQFN (RHR), 5.50 mm x 3.50 mm. Protection functions include VM UVLO, charge-pump undervoltage, overcurrent protection, thermal shutdown, and nFAULT indication.
