LT3750EMS#PBF

Analog Devices · Battery Management ICs · MSOP-10

LT3750EMS#PBF from Analog Devices, in a MSOP-10. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VTRANS power_in Transformer supply pin that powers the transformer primary and the boundary mode detection circuitry; bypass at the pin with a 1µF to 10µF capacitor.
2 DONE output Open-collector indication pin that turns on an NPN when the target output voltage is reached or on a fault such as thermal shutdown or undervoltage lockout; requires a pull-up resistor or current source (absolute maximum 24V, ±1mA).
3 CHARGE input Starts a new charge cycle when driven to 1.1V or higher and shuts the part down when driven below 0.2V, requiring a step input with a minimum ramp rate of 1V/µs.
4 VCC power_in Input supply pin (3V minimum, 24V maximum) to be bypassed locally with a 1µF to 10µF ceramic capacitor.
5 GND power_in Ground pin, connected directly to the local ground plane.
6 SOURCE input Senses NMOS drain current via the NMOS source and current sense resistor, with a current limit of 78mV/RSENSE (1V absolute maximum).
7 GATE output NMOS gate driver output that drives the gate to within VCC - 2V during each switching cycle.
8 RDCM input Discontinuous mode sense pin that detects zero transformer current and starts a new charge cycle through a resistor to the NMOS drain (43k, 5% recommended).
9 RVOUT input Output voltage V-I converter pin that develops a current proportional to the output capacitor voltage through a resistor connected to the NMOS drain.
10 RBG input Output voltage sense pin that disables charging and pulls DONE low when its voltage reaches 1.24V, with a resistor to GND of 2.5k or less recommended (2.49k, 1%).
