SGM2553E
Precision Adjustable Current Limited Power Distribution Switch
 
Precision Adjustable Current Limited Power Distribution Switch
GENERAL DESCRIPTION

The SGM2553E power distribution switch is intended for applications where precision current limiting is required or heavy capacitive loads and short circuits are encountered and provides up to 0.2A of continuous load current. This device offers a programmable current limit threshold between 100mA and 200mA via an external resistor. The power switch rise and fall times are controlled to minimize current surges during turn on/off. The SGM2553E has quick auto-discharge function in disable status.

SGM2553E device limits the output current to a safe level by using a constant-current mode when the output load exceeds the current limit threshold. An internal reverse-voltage comparator disables the power switch when the output voltage is driven higher than the input to protect device on the input side of the switch. The nFAULT output asserts low during over-current, thermal shutdown and reverse-voltage conditions.

SGM2553E is available in a Green TDFN-2×2-6L package. It is rated over the -40 to +85 temperature range.
