LM3658SD-B

Texas Instruments · Battery Management · WSON-10-EP(3x3)

LM3658SD-B from Texas Instruments, in a WSON-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	CHG_IN	power_in	AC wall adapter input pin; the datasheet operating range is 4.5 V to 6.0 V and the absolute maximum is -0.3 V to +6.5 V.
2	USBpwr	power_in	USB power input pin; the datasheet operating range is 4.35 V to 6.0 V and the absolute maximum is -0.3 V to +6.5 V.
3	GND	power_in	Power and signal ground pin, the reference for all voltages; the exposed die-attach pad is also connected to GND and should be soldered to a ground thermal land with vias.
4	USB_sel	input	Pulling this pin low limits the USB charge current to 100 mA, and pulling it high limits the USB charge current to 500 mA.
5	EN_b	input	Pulling this pin low enables the charger and pulling it high disables the charger, with charging interrupted and timers held.
6	STAT2	output	Active-low open-drain charge status output that can drive an LED or GPIO, with IOL specified at up to 10 to 25 mA at 0.25 V.
7	STAT1	output	Active-low open-drain charge status output that can drive an LED or GPIO, with IOL specified at up to 10 to 25 mA at 0.25 V.
8	ISET	passive	A resistor between this pin and GND sets the full-rate charge current on the AC source, with ICHG = KISET/RISET (KISET = 2500 A·Ω typical).
9	TS	input	Battery temperature sense pin that must connect to the battery pack's temperature output; on the LM3658SD-B, leaving it floating indicates no battery and invokes LDO mode (threshold VTLDO 3.95 V to 4.0 V).
10	BATT	power_out	Positive battery terminal connection, which the datasheet says needs a 1 µF capacitor placed as close as possible to the pin; in LDO mode it sources up to 1 A.
11	EP	passive	Exposed pad (from the footprint; not named in the datasheet pin table).
