LP4030HBQVF-87 from LOWPOWER, in a DFN-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	IN	power_in	Positive supply voltage input supporting 4.5V to 20V operation with a 28V absolute maximum rating; place a 1µF ceramic capacitor from IN to PGND as close to the IC as possible.
2	TS	input	Battery temperature sense thermistor input that suspends charging when the battery temperature is out of range, with hot threshold 30% VIN and cold threshold 60% VIN.
3	STAT	output	Open-drain charge status output that is pulled down to GND by an internal N-channel MOSFET while charging and is high impedance when charge is complete; STAT sink current is limited to 10mA absolute maximum.
4	PMID	power_out	Power MOSFET input node that connects to a 10µF ceramic capacitor to ground and should be placed as close as possible to the IC.
5	PGND	power_in	Power ground for the charger power stage, connected to AGND through a single-point connection.
6	AGND	power_in	Analog ground reference for the control and sensing circuitry, connected to PGND at a single point.
7	BST	power_in	High-side MOSFET driver supply input connected to the internal bootstrap diode cathode; connect a 47nF bootstrap capacitor from BST to SW, with BST to SW voltage limited to 6V absolute maximum.
8	SW	passive	Switching node connected to the high-side source and low-side drain that must be connected to the external inductor; SW to GND voltage is rated to 28V absolute maximum.
9	CSP	input	Charge current sensing positive input connected to the external current sense resistor Rcs, with voltage rated to 28V absolute maximum.
10	BAT	bidirectional	Battery voltage sensing and charge current sensing negative input connected to the battery positive terminal, withstanding up to 28V; a 10µF ceramic capacitor is recommended from this pin to PGND.
11	PAD	power_in	Ground reference for the device and thermal pad that conducts heat from the device to the PCB.
