When IC chip temperature rise to 175℃(Typ.), output current is muted, and when IC chip temperature reaches 150℃(Typ.), the driver circuit starts up. When mute-terminal (pin.21) voltage is open or lowered below 0.5V, output current is muted. Under normal use condition, pull up the mute terminal above 1.5V. When bias-terminal (pin.20) voltage is below 0.5V, driver is muted. Under normal use condition, set above 1.1V. When supply voltage falls below 3.8V(Typ.), output current is muted. Next time supply voltage rises to 4.0V(Typ.), the driver circuit start. All drivers are muted by thermal-shut-down. When bias terminal voltage falls and mute is ON, BTL driver except loading driver is muted. Previous stage operational amplifier is no case muted. Output terminal of muted BTL driver applies internal bias voltage (VCC-0.7)/2(V) Loading driver logic input FWD REV VOL (+) VOL (-) FUNCTION ( 1pin ) ( 28pin ) ( 10pin ) ( 9pin ) L L OPEN OPEN OPEN MODE L H L H REVERSE MODE H L H L FORWARD MODE H H L L BRAKE MODE Input circuit of pin1 and pin28 is designed to avoid simultaneous activation of upper and lower output Tr. however, in order to improve reliability, apply motor forward/backward input once through open mode. We recommend time period for open mode longer than 10msec. And, the voltage between the outputs can be controlled with the terminal LDCTL (pin.2). The voltage is set 2.7 times (8.6dB Typ.) LDCTL(pin.2). Insert the by-pass capacitor between Vcc-terminal and GND-terminal of IC as near as possible (approximately 0.1μF). Heat dissipation fins are attached to the GND on the inside of the package. Make sure to be connected to the external GND. In priciple, do not apply voltage below sub-potential of IC to terminal. Examine in consideration of operation margin, when each driver output falls below sub-voltage of IC (GND) due to counter-electromotive-force of load. 2. 3. 4. 5. 6. 7. 8. 9. 10.
