Texas Instruments DRV8256E is a tiny H-bridge motor driver IC that can be used for bidirectional control of a single brushed DC motor at 4.5 V to 48 V. It can supply up to about 1.9 A continuously and can tolerate peak currents up to 6.4 A for a few seconds, making it a good choice for small motors that run on a wide range of voltages. This DRV8256E uses a phase enable interface that allows bidirectional control with only one PWM signal, but it is limited to drive coast operation. The very similar DRV8256P has an IN interface instead, requiring two PWM signals for full bidirectional control, but it offers drive brake operation (which usually provides a more linear relationship between the PWM duty cycle and motor speed).
