IP5305T

INJOINIC · Battery Management · ESOP-8

IP5305T from INJOINIC, in a ESOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	VIN	power_in	5V input charging pin with recommended operation range 4.65-5.5V and overvoltage threshold at 5.5-5.7V.
2	LED1	output	LED display driver pin 1 outputting 2-15mA; selects battery type via pull-down resistor RVSET (43K for 4.3V, 75K for 4.35V, 100K for 4.4V, or floating for 4.2V).
3	LED2	output	LED display driver pin 2 outputting 2-15mA; selects charge display threshold via pull-down resistor RVTHS with five configuration levels (20K, 43K, 75K, 100K, or floating).
4	LED3	output	LED display driver pin 3 outputting 2-15mA for 3-4 LED display modes.
5	KEY	input	Key/button input with debounce time 30-100ms; short press (>30ms, <2s) enables display and boost output; long press (>2s) toggles illumination LED; leave floating when not used.
6	BAT	power_in	Lithium battery positive terminal accepting 3.0-4.4V nominal voltage with low voltage protection threshold at 2.85-3.05V.
7	SW	output	DC-DC converter switching node connected to external inductor; operates at 250-450KHz (discharge mode) or 600-800KHz (charge mode) with PMOS on-resistance 70-90mΩ and NMOS on-resistance 60-80mΩ.
8	VOUT	power_out	5V boosted output pin providing 1.0A maximum output current with regulation voltage 4.75-5.25V and output ripple 20-100mV.
9	EP	passive	Exposed pad (from the footprint; not named in the datasheet pin table).
