LP28013QVF-44 from LOWPOWER, in a TDFN-10-EP(3x3). 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 | VIN | power_in | VIN is the input power source to connect to a wall adapter, with a recommended input supply of 4.5V to 6.5V, an input overvoltage threshold of 7V (typ), and surge protection up to 28V. |
| 2 | CHRG | output | Open-drain charge status output that is pulled low by an internal NMOS during charging and goes high impedance at charge end, requiring an external pull-up resistor, with VSTAT low of 0.1V max at 5mA. |
| 3 | PG | output | Open-drain power-good status output that is low when the input is between UVLO and OVP (3.3V < VIN < 7.0V) and high otherwise. |
| 4 | EN | input | Active-low charge enable input: below 0.4V (or floating) enables the charger, and above 1.4V puts the charger into shutdown. |
| 5 | NTC | passive | Battery thermistor pin biased by an internal ~47-48µA source, designed for a 10k NTC (β=3370) to GND or a fixed 10kΩ if unused, with charging halved at 0°C to 10°C and disabled above 60°C or below 0°C. |
| 6 | GND | power_in | GND is the connection to system ground. |
| 7 | NC | unconnected | No connector pin, listed as 'No Connector' in the datasheet with no function specified. |
| 8 | IBF | passive | Charge status threshold program: an external resistor RIBF to GND sets the termination current via IBF = RISET × IBAT / RIBF, with a programming range of 10% to 50% of IBAT. |
| 9 | ISET | passive | Charge current program: a 1% resistor RISET to GND sets the charge current by IBAT(mA) = VISET × 1500 / RISET(kΩ), with VISET of 1V for RISET = 10k. |
| 10 | BAT | power_out | Battery connection and charger output, requiring a 10µF tantalum capacitor when no battery is attached or a 1µF ceramic capacitor when a battery is attached. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
