LB11947
Overview
The LB11947 is a PWM current control DC motor driver with 5V switching regulator. This IC can simultaneously drive
two DC motors. It is especially suitable for the applications of DC motors that control motor speed with direct PWM
technique using external control signals.
Features
(DC motor drive)
Driving two DC motors.
External PWM control function.
Internal PWM current control (OFF time fixed).
Current decay switching function (SLOW DECAY and FAST DECAY modes).
Noise canceling function.
Output Tr upper diode incorporated (with external lower side Schottky diode).
Thermal shutdown circuit incorporated (with a heat generation warning function).
Logic low-voltage OFF circuit incorporated.
(Switching regulator)
PWM oscillation frequency variable (external C necessary).
Soft start function (external C necessary).
Over-current protection function.
