The LTC1981ES5#TRMPBF is a single high-side N-channel MOSFET gate driver from Analog Devices, configured with an inverting input — the output goes high when the input is pulled low.
Housed in a TSOT-23-5 package (the thin SOT-23 variant), the LTC1981ES5#TRMPBF occupies a 2.9 mm × 1.6 mm footprint with a 0.95 mm pitch — a standard small-signal SMD layout that routes easily on two-layer boards.
It drives the gate of an external N-channel MOSFET configured as a high-side switch. The internal charge pump generates a gate voltage above the supply rail, so the MOSFET can be fully turned on with a logic-level input. Typical applications include battery protection circuits, load switches, and power distribution in portable devices.
The two parts are electrically identical — same gate type, input configuration, supply range, and package. The difference is packaging: #TRMPBF ships in Tape & Reel (minimum full reel quantity) or Cut Tape, while #TRPBF ships in Tape & Reel only. For a board already specified around the #TRPBF, the #TRMPBF drops in without any layout or BOM change.
