SGM2553/SGM2553D Precision Adjustable Current Limited Power Distribution Switches
switches are intended for applications where precision
current limiting is required or heavy capacitive loads
and short circuits are encountered and provide up to
1.5A of continuous load current. These devices offer a
programmable current limit threshold between 100mA
and 1.7A via an external resistor. The power switch rise
and fall times are controlled to minimize current surges
during turn on/off. The SGM2553D has quick autodischarge
function in disable status.
SGM2553 and SGM2553D devices limit 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 devices on the
input side of the switch. The FAULT output asserts low
during over-current, thermal shutdown and reversevoltage
conditions.
SGM2553 and SGM2553D are available in the Green
TDFN-2×2-6L and SOT-23-6 packages. They are rated
over the -40℃ to +85℃ temperature range
