UNISONIC TECHNOLOGIES CO., LTD 82XX Preliminary LINEAR INTEGRATED CIRCUIT MONOLITHIC IC 82XX SERIES  DESCRIPTION The normal operation of the UTC 82XX is that while the power is turned on or interrupted, detect power supply voltage and then reset the system accurately. The internal circuits of the UTC 82XX include a built-in fixed delay time generating circuit. With a counter timer using an analog/digital hybrid circuit, the UTC 82XX as new low reset type system reset ICs expands the delay.

TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8229K Low Frequency Power Amplifier TA8229K is an audio power IC with built-in two channels developed for portable radio cassette tape recorder with power ON/OFF switch. Thermal shut down protection circuit is built in. Features · High power : Pout (1) = 2.5 W (typ.) (VCC = 9 V, RL = 4 Ω, f = 1 kHz, THD = 10%) Pout (2) = 4.6 W (typ.) (VCC = 12 V, RL = 3 Ω, f = 1 kHz, THD = 10%) · Low popping noise at power ON · Small quiescent current : ICCQ = 21 mA (typ.) (VCC = 15 V, Vin = 0) · Soft clip · Built-in thermal shut down protection circuit · Best for supply voltage 9 V, 12 V · Operation supply voltage range: VCC (opr) = 6~15 V (Ta = 25°C) Weight: 3.9 g (typ.) TA8229K 1 2002-03-05 Block Diagram TA8229K 2 2002-03-05 Application Information and Application Method 1. Adjustment of voltage gain The voltage gain Gv is obtained as follows by R1, R2 and Rf in Figure 1. Gv = 20 log Rf + R1 + R2 Rf + R1 When Rf = 0 Ω Gv = 56.5dB (typ.) When Rf = 120 Ω Gv = 45dB (typ.) TA8229K Figure 1 By increasing Rf, reduction of Gv is possible. However, since the feedback increase is liable to produce oscillation, it is recommended to use this at 40dB or over. 2. Thermal shut-down circuit The thermal shut-down circuit is built in for the purpose of preventing the destruction of IC due to the abnormal temperature rise when the heat radiation is insufficient. The operation temperature is set at radiation Fin temperature 17.
