ZXMS82xxxS14PQ IntelliFET® Series Power Switches

Diodes’ dual-channel, high-side power switches provide combined protection for high inrush current loads

Image of Diodes' ZXMS82xxxS14PQ IntelliFET® Series Power SwitchesDiodes’ ZXMS82xxxS14PQ IntelliFETs series of automotive-compliant, dual-channel, intelligent, high-side power switches are designed to handle high inrush current loads while offering robust protection for both the device itself and the connected load. This protection from the integrated controller extends to various potentially damaging events, such as overvoltage, overtemperature, short circuit, and electrostatic discharge.

These switches are particularly well-suited for driving automotive loads, encompassing inductive, capacitive, and resistive loads. Each device features vertical DMOS MOSFETs with respective RDS(ON) (typ. at +25°C); the ZXMS82090S14PQ has 75 mΩ, the ZXMS82120S14PQ has 100 mΩ, and the ZXMS82180S14PQ has 150 mΩ.

The onboard diagnostics detect fault conditions and self-protection events, including open load, overload, and overtemperature shutdown. Additional protection for reverse polarity and loss of ground is easily implemented with minimal additional components. The ZXMS82xxxS14PQ series is available in the thermally efficient SO-14EP package with an exposed underside heatsink.

Features
  • Overvoltage protection, including load dump
    • Protects the device if the battery voltage exceeds the clamp voltage
  • Overtemperature protection with auto-restart
    • Thermal shutdown when TJ max is reached during an overload condition
  • Reverse polarity protection using minimal external components
    • Protects the device should the battery supply be accidentally reversed
  • Diagnostics using current sense
  • Voltage-dependent current limiting
    • Protects the device and the load from an overcurrent condition
  • Loss of ground protection using minimal external components
    • Protects the device and leaves the load OFF should the ground connection be lost
  • Provides a compact dual-channel solution to safely drive automotive loads
  • Enables measurement of load current, monitoring of overall application state, and detection of open load conditions
Applications
  • 12 V automotive loads
  • LEDs
  • Bulbs
  • Actuators
  • Lighting systems
  • Resistive, inductive, and capacitive loads
  • Motors in automotive body controls
  • Relay, fuse, and discrete circuit replacement
