LOWPOWER · Battery Management ICs · TDFN-10-EP(3x3)
LP28300AQVFH 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 | REG | input | Input voltage regulation feedback connected to the tap of a resistor divider from VIN to GND; when REG drops to the inner threshold (VREG reference 1V) the charge current is reduced to hold the input voltage. |
| 2 | VIN | power_in | Positive supply input (4.5V to 18V), to be decoupled with a 10µF or larger surface-mounted ceramic capacitor. |
| 3 | PMID | power_in | Power MOS input pin; connect a 22uF capacitor to ground. |
| 4 | SW | power_out | Switch pin that connects to the external inductor. |
| 5 | GND | power_in | Ground. |
| 6 | NTC | input | Battery-pack thermistor input that stops charging when temperature is out of range (thresholds 30% and 70% of VIN); connect to GND to disable the function. |
| 7 | STAT | output | Open-drain charge status output pulled low by an internal N-channel MOSFET while charging and high impedance in undervoltage lockout (5mA sink, 0.5V max low voltage). |
| 8 | BST | passive | Internal charge pump boost pin. |
| 9 | BAT | bidirectional | Battery pin. |
| 10 | RS | input | Charge current detecting pin, sensing the 50mV reference across the external RSNS resistor to BAT. |
| 11 | GND | power_in | Exposed pad ground, which must be connected to the ground plane for proper power dissipation. |
