DESCRIPTIONThe PT2480 is a brushed-DC motor driver for printers, home appliances, industrial equipment, and other small machines. Dual pin logic inputs controls the Hbridge driver output current flows to maniple the motor rotation in forward or reverse direction. With sufficientheat dissipation PCB area or add-on heatsinking, the peak output current may up to 3.6 Amps.The PT2480 has built-in PWM current regulationcircuits; it’s a very useful function to limiting average current draws from power supply during motor rotates starts up and stalled. The PWM current regulation level is determinates by an external applied VREFreference voltage and current sense resistance attached in ISEN pin.The PT2480 is protected from many fault conditions,including under voltage (UVLO), over current protection (OCP) and over temperature shut down(TSD). The drive will disable the H-bridge output during fault condition is met, and device will automatically recovery when fault phenomena is removed.FEATURES H-Bridge Motor Driver for:– Single brushed DC Motor,– Single Winding of a Bipolar Stepping Motor– Solenoid High Side Driver Wide Operating Voltage : 9V to 45V Low Switches RDS(on) (HS+LS) : 500mΩ(typ) Peak Current Output : 3.6 Amps H-bridge Control Interface PWM Current Regulation Low-Power Sleep Mode Small Package and Footprint– 8-Pin HSOP With Thermal PAD Protection Features– VM Under voltage Lockout (UVLO)– Over Current Protection (OCP)– Over Thermal Shutdown (TSD)– Automatic Fault RecoveryAPPLICATIONS Printers Home Appliances Industrial Equipment可免费提供技术支持样品测试 ***（微信同号）
