However, an AC stabilized (50Hz) power supply should be used to minimize the influence of AC primary side flicker noise on the reading. *3: Use the designated transformer power supply circuit shown in the figure below for allowable load shorted time and output noise voltage measurement. *4: Use the standby pin (pin 1) so that the applied voltage never exceeds the maximum rating. The power amplifier is turned on by applying +2.5V to +5.5V to the standby pin (pin 1). *5: The -Pre VCC (pin 6) must be at the lowest level under any circumstances so that the reverse-bias current does not flow. * Thermal design must be implemented based on the conditions under which the customer’s end products are expected to operate on the market. * The weight of hybrid IC alone: 15g Package dimensions (length×width×height): 502mm×247mm×282mm No. A1244-2/12 STK404-230-E DBA40C 10000μF + +VH 500Ω Designated transformer power supply (MG-250 equivalent) + 500Ω -VH Package Dimensions unit:mm (typ) 59.2 52.0 8.5 5.6 11.0 16.0 25.5 3.6 1 2.54 13 4.0 20.8 2.9 0.4 0.5 5.5 (10.76) 12 2.54=30.48 Internal Block Circuit +VCC 11 +PRE 7 Pre Driver CH1 13 OUT+ IN NF 3 4 DC offset detector 8 DC 12 OUT- -PRE 6 Stand-by circuit Latch circuit Overcurrent detector 9 OC SUB 5 SUB /GND 1 2 10 -VCC STBY ERROR No. A1244-3/12 STK404-230-E Test Circuit STK404-230-E ST SUB BY ERROR IN NF /GND -Pre +Pre DC OC -VCC +VCC OUT- OUT+ 1 R30 2 3 4 5 6 7 8 9 10 11 12 13 R25 *1 R24 *1 OC DC Stand-by H: Operation L: Standby/Error reset C22 ERROR H: Operation L: Error (open collector) R21 IN C19 GND R05 C16 VDC L01 R14 R18 R11 C07 C13 R03 +VCC C01 C05 GND C06 C02 -VCC R04 C10 R08 OUT GND VOC *1 Metal plate cement resistor: 0.22Ω±10% (5W) Pin Description Pin No. 1 2 3 4 5 6 7 8 9 10 11 12 13 Pin name STBY ERROR IN NF SUB/GND -PRE +PRE DC OC -VCC +VCC OUTOUT+ I O I I G V V I I P P O O Standby terminal H: Operation mode, L: Standby mode Error signal output in protection mode (open collector) H: Operation mode, L: Protection mode (shutdown) Input signal terminal NF signal input terminal Ground terminal, circuit ground and sub-ground Negative power supply for predriver Positive power supply for predriver DC offset detection signal input L: Protection disabled, H: Protection enabled (system shutdown) Overcurrent detection signal input L: Protection disabled, H: Protection enabled (system shutdown) Negative power supply for power Positive power supply for power Negative output terminal (emitter of PNP power transistor) Positive output terminal (emitter of NPN power transistor) Function No. A1244-4/12 STK404-230-E Recommended External Parts Symbol R03, R04 R05 R08 R11 R14 R18 R21 R24, R25 R30 C01, C02 Recommended Value 100Ω/1W 56kΩ 4.7Ω/1W 4.7Ω 1.8kΩ 56kΩ 1kΩ 0.22Ω±10%, 5W Remarks *4 100μF/100V Description Ripple filtering resistors (Use of fusing resistors is desirable.
