SGM2553/SGM2553D Precision Adjustable Current Limited Power Distribution Switches

PublishTime：2020-06-09

The SGM2553 and SGM2553D power distribution 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 100mAand 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 auto-discharge 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 reverse- voltage conditions.SGM2553 and SGM2553D are available in the GreenTDFN-2×2-6L and SOT-23-6 packages. They are rated over the -40°C to +85°C temperature range.
