Application Information
1. Power Save Function
Power save function is also performed at PS (pin20). The truth table is as follows:
Figure 1. Truth table of Gain selection and Mute Function
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
°
C, then the 4-channels BTL driver output circuit will be muted.
The TSD circuit has the hysteresis temperature of 25
°
C.
4. Balanced Transformerless(BTL) Driver (CH1, CH2 and CH3)
CH1, CH2 and CH3 drive parts are composed of internal filter, V-I converter and output power amplifiers.
