Quad High Side Switch
(Quad 35 mOhm)
35XS3400
The 35XS3400 is one in a family of devices designed for low-voltage
automotive lighting applications. Its four low RDS(ON) MOSFETs (quad
35 mOhm) can control four separate 28 W bulbs, 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. The 35XS3400 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 functionality of the
outputs in case of MCU damage. This device is powered by
SMARTMOS technology.
HIGH SIDE SWITCH
Features
• Four protected 35 m high side switches (at 25 °C)
• Operating voltage range of 6.0 V to 20 V with standby current <
5.0 A, 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 protection with time limited autoretry, and Fail-safe
mode in case of MCU damage
• Output OFF or ON OpenLoad detection compliant to bulbs or
LEDs and short to battery detection
• Analog current feedback with selectable ratio and board
temperature feedback

Notes
27. Rise and Fall Slew rates measured across a 5.0 resistive load at high side output = 30% to 70% (see Figure 4, page 16).
28. Turn-ON delay time measured from rising edge of any signal (IN[0:3] and CS) that would turn the output ON to VHS[0:3] = VPWR / 2 with
RL = 5.0 resistive load.
29. Turn-OFF delay time measured from falling edge of any signal (IN[0:3] and CS) that would turn the output OFF to VHS[0:3] =VPWR / 2
with RL = 5.0 resistive load.
