SGM40677

Active

Current Limit Switch with Over-Voltage Protection and True Reverse Current Blocking, 28V/5.5A Rated

The SGM40677 is current limit switch that can offer 28V/5.5A rated capability. It provides rich system protections including over-current protection (OCP), true reverse current blocking (TRCB), over-voltage protection (OVP), under-voltage protection (UVP), over-temperature protection (OTP) and short-circuit protection (SCP). The SGM40677 features 18mΩ low on-resistance with WLCSP package. The input operating voltage is 4V to 22V.

The SGM40677 provides accurate current limit protection. Besides, the device offers adjustable over-voltage protection, configurable ON polarity and configurable over-current threshold action, which help meet various system applications.

The SGM40677 is available in a Green WLCSP -1.66×2.54-24B package.
