Brushed DC Motor driver with Dual H-bridge mode

Features

• Supporting large current (9.0 A) and high voltage (50 V) brushed DC motor operation.

• Capable of driving two brushed DC motors using dual H-Bridge mode.

• Capable of driving one stepping motor using dual H-bridge mode.

• Built-in sense resistor less current control. (ACDS: Advanced Current Detection System)

• Low Rds (on) MOSFETs (High side+ Low side=0.33 Ω (typ.))

• Error detection features (Thermal shutdown (TSD), Over current detection (ISD), Power-on-reset (POR),

and Motor load open detection (OPD))

• Error detection signal output (Error Output)

• Internal VCC (5 V) regulator enables the driver to be operated with a single power supply (VM).

• Adjustable constant current PWM frequency using external components.

• Small package with thermal pad. (QFN48: 7.0 mm x 7.0 mm)
