Quad High Side Switch
(Dual 10 mOhm, Dual 35 mOhm)
The 10XS3435 is one in a family of devices designed for low-voltage
automotive lighting applications. Its four low R
DS(ON)
MOSFETs (dual
10 mOhm/dual 35 mOhm) can control four separate 55 W / 28 W
bulbs, and/or Xenon modules, and/or LEDs.
Programming, control and diagnostics are accomplished using a
16-bit SPI interface. Its output with selectable slew-rate improves
electromagnetic compatibility (EMC) behavior. Additionally, each
output has its own parallel input or SPI control for pulse-width
modulation (PWM) control if desired. The 10XS3435 allows the user to
program via the SPI the fault current trip levels and duration of
acceptable lamp inrush. The device has fail-safe mode to provide fail-
safe functionality of the outputs in case of MCU damaged.
Features
• Four protected 10 mΩ and 35 mΩ high side switches (at 25°C)
• Operating voltage range of 6.0 V to 20 V with sleep current <
5.0
μA,
extended mode from 4.0 V to 28 V
• 8.0 MHz 16-bit 3.3 V and 5.0 V SPI control and status reporting
with daisy chain capability
• PWM module using external clock or calibratable internal
oscillator with programmable outputs delay management
• Smart over-current shutdown, severe short-circuit, over-
temperature protections with time limited autoretry, and fail-safe
mode in case of MCU damage
• Output OFF or ON open-load detection compliant to bulbs or leds
and short to battery detection. analog current feedback with
selectable ratio and board temperature feedback.
• Pb-free packaging designated by suffix code DPNA
