Product Details

Description



Features:

•4-channel Balanced Transformerless (BTL) Driver
•3-channels PWM input direct-coupled type include internal filters.
•Separated power supply voltages
(PVCC1: CH1 and CH2, PVCC2: CH3 and CH4)
•Built-in input pin selection function of channel 4
•Built-in OP-amplifier
•Built-in Power Save function
•Built-in Thermal Shutdown Circuit (TSD)
•Operating ranges: 4.5~ 13.2V


Application

1. Power Save Function
•Power save function is also performed at PS (pin20). The truth table is as follows:
•When the PS (pin 20) is hige level (above 2V), the bias circuit is enable. On the other hand, when the PS(pin20) is low level (under 0.5V), the bias circuit is disabled.
•When the CAPA(pin3) is low level, the CAPA (pin25) is opened in Figure. 4.
2. TSD (Thermal Shutdown) Function
•When the chip temperature rises above 175, then the 4-channels BTL driver output circuit will be muted.
The TSD circuit has the hysteresis temperature of 25.
