Compact new load switch provides comprehensive protection functions

The Littelfuse LS0504EDD12 load switch has low on-resistance and low shut-down current, making it ideal for use in battery-powered systems such as wearable devices and wireless headsets.

The Littelfuse LS0504EDD12 is a compact load switch which provides circuits with protection against over-current, over-voltage, over-temperature events, as well as limiting inrush current.Ā 

Featuring low on-resistance of 26 mĪ© and low shut-down current, the LS0504EDD12 is ideal for applications that require both robust protection and low power consumption.

The LS0504EDD12 provides an accurate 1.2 V enable threshold that allows designers to set the under-voltage lockout (UVLO) limit through an external resistor-divider network. It has a built-in 8 Ī© resistor for quick output discharge when disabled.

Other new additions to the Littelfuse portfolio of protection ICs are:

  • LS12052BD33 series – 18 V/5 A-rated, provides over-voltage protection and blocking FET controlĀ 
  • LS2405IDD23 series – 24 V/5 A-rated. Diode has very low forward voltageĀ 
  • LS24062RQ23 series – 28 V/6 A-rated bi-directional eFuse with dual-port independent limit setting
