(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. 6) Loading driver input logic truth table FWD (1pin) REV (2pin) VOL+ (10pin) VOL- (9pin) Function L L OPEN OPEN Open L H H L REV H L L H FWD H H L L Play HANGZHOU SILAN MICROELECTRONICS CO.,LTD Http: www.silan.com.cn REV:2.1 2006.09.11 Page 4 of 8 SA5810 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.

When supply the power, please tune up the IC to pulse kon (0.1µF). 2. Even though the radiation fins are connected to ground within the package, be sure to also connect them to a ground externally as well. 3. When use the PREVCC, POWVCC12 or POWVCC34 separately, the POWVCC12 and POWVCC34 cannot exceed the PREVCC. 4. Generally, we should avoid lettering at the pins whose voltage is lower than SUB voltage, because the loading driver causes the “inverse voltage”; when the SUB voltage is lower than the ground, should consider the margin problem. 5. In the circuit, should avoid the short circuit between the output pin and POWVCC pin, or output pin and the ground pin. When assemble the circuit to bias board, must be attention the position/direction of circuit, if the circuit disrepair, it even smoky at some conditions.
