• Manufacturer Part Number: STK433-760-E
• Description: 2-channel class AB audio power IC 50W+50W
• Manufacturer: Sanyo Semicon Device

[Remarks]
*1: Maximum ratings are limits beyond which damage to the device may occur.
*2: For 1-channel operation
*3: -Pre V CC (pin 7) must be connected to the lowest stable potential to prevent the current flowing into the pin 1 due to
*4: Thermal design must be implemented based on the conditions under which the customer’s end products are expected
*5: Use the hybrid IC so that the voltage applied to the stand-by pin (pin 13) never exceeds the maximum rating. The
*6: An output limiting circuit for H-IC overheating is incorporated to protect the hybrid IC from the heat generation
*7: The load short-circuit protection is designed based on the specification test condition.
*8: The substrate temperature protection rating is the design guarantee value using the specification test circuit of
*9: A thermoplastic adhesive resin is used to secure the case and aluminum substrate. For this reason, the hybrid IC
*10: Use the designated transformer power supply circuit shown in the figure below for the measurement of allowable
*11: Weight of independent hybrid IC: 12.2g

to operate on the market.
power amplifier is turned on by applying +2.5V to +5.5V to the stand-by pin (pin 13).
exceeding the maximum rating. Thermal design must be implemented from the maximum loss Pd max and "Pd-Tc"
derating curve based on the conditions under which the customer's end products are expected to operate on the
market. When deviating from the "Pd-Tc" derating curve, the desired output is not obtained, but the prescribed
output is generated again by reducing H-IC temperature to within the recommended operating region.
The load short-circuit protection circuit is activated when it has detected an overcurrent in the output transistors. So
if any deviation from the "Pd-Tc" derating curve occurs, the protection circuit is activated and the circuit shuts down
in order to protect the output transistors. When the load short-circuit protection circuit has been activated and the
circuit shuts down, approximately +5.5V of voltage will be placed at the MONITOR pin (pin 10) (normally 0V).
The protection circuit operation is released by establishing the stand-by mode (pin 13: 0V).
SANYO Semiconductor.
The output limiting circuit for H-IC overheating (*6) and the load short-circuit protection circuit (*7) are the only
protection functions incorporated.
The thermal design and overcurrent protection level must be verified based on the conditions under which the
customer's end products are expected to operate on the market.
must be fixed to the heat sink before soldering and mounted. The heat sink must be installed or removed at room
temperature.
Exceeding the maximum ratings, even momentarily, may cause damage to the hybrid IC.
In SANYO Semiconductor's test processes, operation at the maximum supply voltage is checked.
(Test conditions) V CC max (2)=±33V, R L =4Ω, f=1kHz, Po=35W, 1ch Drive, ton=25ms, Tc=25°C
