Dual-channel H-bridge current-controlled motor driver: single or dual brushed DC motors, one stepper motor. Current control at fixed frequency is optional: 2 bits current control, providing 4 current steps. Low On-Resistance Metal Oxide Semiconductor Field Effect Transistor (MOSFET): 4.0A Maximum Drive Current at 24V, Ta = 25°C; 300mΩ RDS(on) at 24V, Ta = 25°C (Typical HS + LS). The maximum working withstand voltage is 50V. sleep mode low current. Built-in 3.3V reference voltage. Surface mount encapsulation with heat sink. Protection features: Overcurrent Protection (OCP); Thermal Shutdown (TSD); Undervoltage Lockout (UVLO); Fault Display Pin (nFAULT).
