PT2484 Datasheet | Princeton Technology

DESCRIPTION The PT2484/PT2484A is a dual channel H-bridge motor driver that operates on wide supply voltage range from 4V to 16V. Four individual control logic pins provides flexibility to drives a 4-wire bipolar stepping motor or two brushed dc motors or solenoid load. The chip has built-in protection circuit to prevent the short circuit or over temperature event to damage the H-bridge driver. APPLICATIONS - Airflow flap control for refrigerators. - Air Conditioner venting control - Home appliance - Office automation machines PT2484/PT2484A Dual H-Bridge Motor Driver Features - Wide Supply Voltage Range: 4V to 16V - Single voltage supply with built-in regulator; control logic supply is not necessary. - Dual H-bridge Drivers for a bipolar stepping motor or two brushed dc motors. - MOSFET RDS(on) Resistance HS + LS =1.2Ω - Maximum Output Current: 1A (Peak), 700m A (RMS). - Low Power Stand-by mode - Built-in Protection Circuits with Thermal Shutdown (TSD), Under Voltage Lock-Out (UVLO) - Output current limiting (OCL) during load terminal connects to GND. - 10Pins Small Outline Package (SOP), Pitch=1.0mm. 10Pins Small Outline Package (MSOP), Pitch=0.5mm.
