LTC1694CS5#TRMPBF

Analog Devices · Interface - Specialized · TSOT-23-5

LTC1694CS5#TRMPBF from Analog Devices, in a TSOT-23-5. 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 VCC power_in Power supply input; VCC can range from 2.7V to 6V and requires a 0.1µF bypass capacitor to GND.
2 GND power_in Ground reference for the device.
3 NC unconnected No connection; this pin is not used by the device.
4 SMBus2 bidirectional Active pull-up for the SMBus line: pull-up current is 125µA to 350µA with the bus at 0V, boosting to 2.2mA typical on positive transitions, with inputs rated from -0.3V to (VCC + 0.3V).
5 SMBus1 bidirectional Active pull-up for the SMBus line: pull-up current is 125µA to 350µA with the bus at 0V, boosting to 2.2mA typical on positive transitions, with inputs rated from -0.3V to (VCC + 0.3V).
