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) = 0.7V (max.)) * 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.

Pin Connection (side view) 1 2002-10-30 TD6304,08AP Block Diagram Pin Description Pin No. Symbol Designation Function 1 Prog Program switch terminal Terminal used for forcing plunger output on regardless of state of rotation detecting output / input. However, one output only is transmitted per operation. 2 Input Rotation detecting signal input terminal Rotation detecting pulse input terminal. Plunger output is transmitted at certain time after input is stopped. 3 OSC Oscillator terminal Terminal used for connecting oscillation capacitor and resistor for setting response time and driving time of plunger output, when COSC = 0.22F, ROSC = 30k, fOSC500Hz is attained. 5 E-out Emitter output terminal Emitter output of output transistor is transmitted. Further, this terminal is used for darlington connection with an externally mounted transistor. This terminal is normally earthed to GND through a resistor. 6 Out Plunger output terminal Plunger driving output terminal. Vsat = 0.7V and IOUT = 200mA are transmitted when 5 pin is earthed. (open collector) 7 VCC Power terminal Supply voltage VCC = 8.0~16.0V is applied. 4 GND Earth terminal For grounding 2 2002-10-30 TD6304,08AP Outline Of Function (1) How to decide oscillator frequency COSC and ROSC are an externally mounted resistor and capacitor deciding oscillator frequency, respectively. TOSC can be calculated from above calculating formula, but when TOSC - ROSC graph is used, COSC and ROSC deciding desired oscillator frequency can be selected easily. (2) Plunger output when pulse input is stopped. Output wave form and timing are as follows. (a) In case of TD6304AP T1: Plunger response time typical 0.75s T2: Plunger drive time typical 0.25s (when fOSC500Hz) (when fOSC500Hz) Above T1 and T2 can be calculated from the following formula: (b) T1 = 3 x 512 x TOSCs 4 T2 = 1 x 512 x TOSCs 4 In case of TD6308AP T1: Plunger response time typical 0.88s T2: Plunger drive time typical 0.12s (when fOSC500Hz) (when fOSC500Hz) T1 and T2 can be calculated from the following formula: T1 = 7 x 512 x TOSCs 8 T2 = 1 x 512 x TOSCs 8 3 2002-10-30 TD6304,08AP (c) (3) Method for selecting T1 and T2 from graphs. Externally mounted capacitor and resistor for plunger response time T1 and plunger drive time T2 can be easily selected when T1, T2 - COSC, ROSC graphs are used. For instance, in case of TD6304AP, if it is desired to set plunger response time T1 at 1s, when COSC = 0.47F is used at plunger response time shown by dotted line, ROSC is approx. 20k and the plunger drive time T2 shown by solid line will be 0.34s. Other COSC can also be selected in the same manner. When COSC = 0.33F, ROSC30k, T20.34s When COSC = 0.22F, ROSC47k, T20.34s and values of T1 and T2 do not change even when C and R constants are changed. T1 and T2 of TD6308AP can be selected in the same manner as in TD6304AP. Duty cycle is, TD6304AP T1: T2 = 3 : 1 TD6308AP T1: T2 = 7 : 1 Plunger output when program switch is operated. Output wave form and timing are as follows. T2: Plunger drive time In case of TD6304AP, T2 is 0.25s (when fOSC500Hz) In case of TD6308AP, T2 is 0.12s (when fOSC500Hz) Actually, output is transmitted only one time within 50ms after program switch is operated. 4 2002-10-30 TD6304,08AP Maximum Ratings (Ta = 25C) Characteristic Symbol Rating Unit Supply voltage VCC 30 V Output voltage VOUT 30 V Output current IOUT 400 mA Power dissipation PD 400 mW Operating temperature Topr -30~75 C Storege temperature Tstg -55~150 C Electrical Characteristics (unless otherwise specified, VCC = 13.2V, Ta = 25C) Characteristic Symbol Test Circuit VCC ICC1 Min.
