Application Information
1. Mute Function
When The BRAKE Pin is low is normal opration (high is CH1 mute on).
When The Mute2 Pin is low is normal opration (high is CH2 mute on).
When The Mute34 Pin is high is normal opration (low is CH3,4 mute on).
2. Vref Drop Mute (Figure 1)
When the Voltage of the mute pin is above 1V, the mute circuit is stopped and the output circuit is.
3. Thermal Shutdown(Figure 2)
If the chip temperature rises above 150
°
C, then the thermal shutdown (TSD) circuit is activated and the output circuit will
be mute.
4. H-bridge Driver (4-Channels)
Driver input resistance is 10k
of CH1, CH3, CH4 and input resistance of CH2 is 7.5k
.
Driver gain can obtain under -mentioned
R is External resistance.
