MP8042
The Future of Analog IC Technology
MP8042
24V, 5A Dual Channel Power Half-Bridge
DESCRIPTION
The MP8042 is a configurable full-bridge or
dual channel half-bridge that can be configured
as the output stage of a Class-D audio amplifier.
Each channel can be driven independently as
stereo single ended audio amplifiers, or driven
complementary in a bridge tied load (BTL)
audio amplifier configuration.
The MP8042 features a low current shutdown
mode, standby mode, input under voltage
protection, current limit, thermal shutdown and
fault flag signal output. Both channels of the
driver interface with standard logic signals. The
MP8042 is available in a 20-pin TSSOP (with
Exposed Pad) package.
FEATURES
±5A Peak Current Output
Up to 600kHz Switching Frequency
Protected Integrated 150mPower Switches
30ns Switch Dead Time
All Switches Current Limited

Operating Junct. Temp (TJ)...... -40°C to +125°C
Thermal Resistance (4) θJA θJC
TSSOP20F..............................40 ....... 6 .... °C/W
Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature TJ (MAX), the junction-to-
ambient thermal resistance θJA, and the ambient temperature
TA. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by PD (MAX) = (TJ
(MAX)-TA)/θJA. Exceeding the maximum allowable power
dissipation will cause excessive die temperature, and the
regulator will go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanent
damage.
3) The device is not guaranteed to function outside of its
operating conditions.
4) Measured on approximately 1” square of 1 oz copper.
