PT2480 DC马达驱动芯 完美替代 DRV8870 A4950 TR8800 3.6A马达驱动芯片

DESCRIPtiON
The PT2480 is a brushed-DC motor driver for printers,
home appliances, industrial equipment, and other
small machines. Dual pin logic inputs controls the H
bridge driver output current flows to maniple the motor
rotation in forward or reverse direction. With sufficient
heat dissipation PCB area or add-on heatsinking, the
peak output current may up to 3.6 Amps.
The PT2480 has built-in PWM current regulation
circuits; 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 VREF
reference 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.
