• Manufacturer Part Number: stk404-200-e
• Description: One-channel Class Audio Power Amplifier
• Manufacturer: Sanyo Semiconductor Corporation

Applications
Standby circuit
Use the current limiting resistor R1 (*1) so that the voltage applied to the Stand-by pin (pin #1) does not exceed the
maximum rating voltage.
Standby control voltage (V)
This pin has a function to release the latch when it is set to the ground level.
Overcurrent Protection Circuit
Overcurrent protection is activated if VOC ≈ 0.5V (typ) is applied to OC (#9). The HIC shuts down (latch mode) and
the state of the error pin switches from high to low. The (open collector output) latch mode is cleared by setting the pin
to the ground level.
