SE2513-HF

Seaward Elec · Battery Management · SOT-23-6

SE2513-HF from Seaward Elec, in a SOT-23-6. 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 DP1 bidirectional Channel 1 USB D+ data-line port; the absolute maximum voltage from DP1 to GND is -0.3 V to 7 V, and it is driven to the divider or 1.2 V charging levels selected by SEL.
2 GND power_in Reference ground for the device.
3 DP2 bidirectional Channel 2 USB D+ data-line port; the absolute maximum voltage from DP2 to GND is -0.3 V to 7 V, and it is driven to the divider or 1.2 V charging levels selected by SEL.
4 DM2 bidirectional Channel 2 USB D- data-line port; the absolute maximum voltage from DM2 to GND is -0.3 V to 7 V, and it is driven to the divider or 1.2 V charging levels selected by SEL.
5 IN power_in Power input for the device, specified for 4.5 V to 5.5 V operation with an absolute maximum of -0.3 V to 7 V to GND and an undervoltage lockout of about 4.1 V (typical).
6 DM1 bidirectional Channel 1 USB D- data-line port; the absolute maximum voltage from DM1 to GND is -0.3 V to 7 V, and it is driven to the divider or 1.2 V charging levels selected by SEL.
