Motor drivers lower RDS(ON) by more than 60 percent
Microstepping options within the family include up to 256 microsteps and greater with an external microcontroller or up to 32 microsteps with an on-chip indexer.
The bipolar stepper motor drivers provide 2.5-A to 5-A peak current options and control interfaces for phase-enable (PH/EN), step/direction with indexer and pulse-width modulation (PWM) control.
Support for 1/256 and greater microstepping, along with slow, mixed and fast decay modes, provide for smooth, quiet, high-resolution motion profiles in applications such as printers, scanners, security cameras, cash handlers, medical equipment and factory automation.
The brushed DC motor drivers offer 2.5-A to 5-A peak current options and control interfaces for PH/EN and PWM control. On-chip cycle-by-cycle inrush protection limits start-up and stall currents, protecting the driver and reducing overall system cost in a variety of applications, such as printers, robotics, toys, servo motors, textile manufacturing equipment, solenoid valves and consumer electronics.
Advanced on-chip protection, including over-current, over-temperature, shoot-through and under-voltage lock-out increases system reliability and manufacturing yields. TI also states that DRV8x motor drivers integrate the gate drive circuitry, MOSFETs, protection circuitry and current regulation circuitry to reduce design complexity, board space and time to market compared to discrete solutions.
