TD6304,08AP
TOSHIBA Bipolar Digital Integrated Circuit Silicon Monolithic
TD6304AP,TD6308AP
Auto Reverse & Auto Eject Plunger Driver
TD6304AP, TD6308AP are IC developed for auto reverse / auto eject on a car stereo.
There are two methods for driving the plunger; one is to drive it after motor rotation detecting signal is stopped and the other is to drive it optionally by program switch.
Further, this IC can be used as a solenoid driver in the control circuit of a stereo, remote control system and other electric accessories.
Features
· Plunger driving output transistor is built in.
No.
6 pin output IOUT = 200mA (VCE (sat) = 0.

· Manual operation by program switch is possible.
· Time for output pulse generation after rotation detecting
signal is stopped and output pulse width are variable by external mounted capacitor and resistor.
(Duty cycle of output pulse is set inside IC)
· A load dump circuit is built in for protection from overvoltage.
· Operating supply voltage VCC (opr) = 8~16 V (7 pin voltage)
· TD6304AP is 1 / 4 duty cycle.
· TD6308AP is 1 / 8 duty cycle.

Function
Terminal used for forcing plunger output on regardless of state of rotation detecting output / input.
However, one output only is transmitted per operation.
Rotation detecting pulse input terminal.
Plunger output is transmitted at certain time after input is stopped.
Terminal used for connecting oscillation capacitor and resistor for setting response time and driving time of plunger output, when COSC = 0.
22µF, ROSC = 30kΩ, fOSC≒500Hz is attained.
Emitter output of output transistor is transmitted.
Further, this terminal is used for darlington...
