The IP4504A is a 5-CH motor driver for CD-P/VCDP/
DVDP systems. It is composed of 2-CH BTL driver, 2-
CH BTL driver with current feedback and 1-CH
forward/reverse controlled DC motor driver.
- 2-CH BTL driver
- 2-CH BTL driver with current feedback
- 1-CH forward/reverse controlled DC motor driver
- Built-in motor speed control circuit
- Built-in TSD (thermal shut down) circuit.
- Built-in mute circuit excluding CH1.
- Operating supply voltage (4.5V~13.2V).
