UASS101 - MAGIC SWITCH

General Description

The UTC UASS101 is a Magic Switch to remove Phantom Power consumption.

An equivalent circuit has been provided in Fig1.

The Phantom Power consumption due to EMI Cap.’s discharge resistor can be removed by a pretty simple circuit as described in the block diagram.

Key Features

  • Remove Phantom Power consumption.
  • Meet safety ICE 60065/60950.
  • ~1KV Break down voltage.
  • For lightning surge sensitive environment.
  • Can work with any EMI’s capacitor filter.
  • Most cost effective, Layout easy solution, easily to meet Erp lot6 tier 2 requirement.

UNISONIC TECHNOLOGIES CO., LTD UASS101 Preliminary LINEAR INTEGRATED CIRCUIT MAGIC SWITCH  DESCRIPTION The UTC UASS101 is a Magic Switch to remove Phantom Power consumption. An equivalent circuit has been provided in Fig1. The Phantom Power consumption due to EMI Cap.’s discharge resistor can be removed by a pretty simple circuit as described in the block diagram. However, Magic Switch could be most cost-effective, layout easy…..choice for designing zero no load consumption application. The UTC UASS101 behaves like a magic switch or a low-pass filter. It allows DC passes and AC is blocked. The UTC UASS101 allows frequency more than 20 Hz to pass (AC plug-in Magic switch turn off) with ~ Zero Input Power. Magic switch is turn on discharge EMI’s Cap when frequency small than 20Hz.
