STK433-730-E
No. A1249-3/12
[Remarks]
*1: Maximum ratings are limits beyond which damage to the device may occur.
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) VCC max (2)=±25V, RL=4Ω, f=1kHz, Po=15W, 1ch Drive, ton=25ms, Tc=25°C
*2: For 1-channel operation
*3: -Pre VCC (pin 1) must be connected to the lowest stable potential to prevent the current flowing into the pin 1 due to
reverse bias, etc.
*4: Thermal design must be implemented based on the conditions under which the customer’s end products are expected
to operate on the market.
*5: Use the hybrid IC so that the voltage applied to the stand-by pin (pin 13) never exceeds the maximum rating. The
power amplifier is turned on by applying +2.5V to +5.5V to the stand-by pin (pin 13).
*6: An output limiting circuit for substrate overheating is incorporated to protect the hybrid IC from the heat generation
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 the substrate temperature to within the recommended operating region.
*7: The load short-circuit protection is designed based on the specification test condition.
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 +6.2V 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).
*8: The substrate temperature protection rating is the design guarantee value using the specification test circuit of
SANYO Semiconductor.
The output limiting circuit for substrate 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.
*9: A thermoplastic adhesive resin is used to secure the case and aluminum substrate. For this reason, the hybrid IC
must be fixed to the heat sink before soldering and mounted. The heat sink must be installed or removed at room
temperature.
*10: Use the designated transformer power supply circuit shown in the figure below for the measurement of allowable
load shorted time and output noise voltage level.
*11: Weight of independent hybrid IC: 12.2g
