Note: Positive output and negative output are the polarities with respect to the input. (For example, if pin5 voltage
is high, then pin 14 voltages become high.)
FUNCTION DESCRIPTION
1) This IC has a built in thermal shutdown circuit that mutes the output current when the chip temperature
reaches 175(°C (typ.). The hysteresis is set to 25 (°C (typ.), so the driver circuits start up again when the chip
temperature falls to 150(°C (typ.).
2) The driver buffer is switched off when the supply voltage falls below 3.8V (typ.), and is switched back on
when the voltage reaches 4.0V (typ.) again.
3) Bias pin (pin28) should be pulled up to more than 1.1V. In case the bias pin voltage is pulled down below
0.7V (Typ), the output current is muted.
4) Mute is applied when the mute pin voltage falls below 0.5V (typ.). Normally, operate with this pin at 1.5V at
least.
5) If the power supply is too low, the internal thermal shutdown circuit will mute the driver. When the mute on,
and bias voltage is low, BTL driver (except loading driver) will mute, but the pre-amplifier will not mute at
anytime. When muting occurs, the output voltage of BTL driver is POWVCC/2V.

The design of 1,2 pin, consider the driver upper and lower unable ducting at the same time, be sure to do
it, the motor forward and reverse input by the open mode, and the interval of the open mode is more than
10ms.
Output high level voltage (VOL+, VOL-), varied with the motor controller, it can output 3 times voltage of 3
pin, and in high level. In this time, the low level voltage input power pipe as the output saturation voltage.
