Output current ratings: 2.0 A (max)
Low on-resistance (High + Low side = 0.48 Ω (typ.)) MOSFET output stage
Built-in Sense resistor less current control architecture (Advanced Current Detection System)
Multi error detect functions (Thermal shutdown (TSD), Over current (ISD)) and Under voltage lockout(UVLO))
Error detection (TSD/ISD) flag output function
Built-in VCC regulator for internal circuit
Chopping frequency of a motor can be adjusted by external resistor
Selectable Forward / Reverse / Stop / Brake modes
Small QFN package with thermal pad (16pin)
Note: Please be careful about thermal conditions during using.
