MUTE •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.). •The mute circuit logic is active low. •The circuit is muted during thermal shutdown and during the mute-on state .In each case, only the drivers are muted. The output pins remain at the internal bias voltage, roughly (Vcc – Vbe) / 2. •Bias pin (pin23) should be pulled up to more than 1.6V. In case the bias pin voltage is pulled down below 1.4V (Typ), the output current is muted. 2. Regulator This is a typical series regulator that generates a reference voltage internally. A PNP low saturation type transistor must be connected. + - REG Attached PNP VOUT VREF REO Oscillation prevention •VREF BG is the output voltage of the bandgap standard bias circuit and is also the standard voltage of the regulator. HANGZHOU SILAN MICROELECTRONICS CO.,LTD Http: www.silan.com.cn REV:1.3 2007.01.26 Page 4 of 10 SA9259 • Periphery circuit is composed of bipolar, KSB722 and one 100µF capacitor. The capacitor needs good temperature characteristics to remove the ripple. •The output voltage VOUT is decided by the following formula: VOUT = VREF BG (R2 + R3) / R3 = 2.5 X 2 = 5V R2 = R3 3. LOADING MOTOR DRIVER •Input voltage (5V and 0V or 0V and 5V to pin 9 and pin 14. •After input the voltage to pin 9 and pin 14, decide the output of comparator according to the voltage state. •As the above figure, the voltage warp ∆V, [VREF1 + (I x R)] - [VREF1 -(I x R)], used for the motor. And the direction of the motor is decided by the voltage warp +∆V and -∆V. •The output characteristics are as follows: FWD(pin9) REV(pin14) VOTR+(pin15) VOTR-(pin16) Function L L (Vcc – Vbe) / 2 (Vcc – Vbe) / 2 Stop mode L H L H Reverse mode H L H L Forward mode H H (Vcc – Vbe) / 2 (Vcc – Vbe) / 2 Stop mode 4. LOADING MOTOR SPEED CONTROL VCC(8V) VCC(8V) 50K 4V 20 50K R VCC 4V 50K 20 R VCC 50K •If the torque of the loading motor is too low when it is used with the pin #20 open, then it should be used as the above diagram. •The desired torque could be obtained by selecting the appropriate resistor R as shown in the left diagram. •If it is necessary, the zener diode can be used as in the right diagram. •The maximum torque is obtained when the applied voltage at pin #20 is about 6.8V (at VCC=8V). 5.
