ETA6005Q3Q

etasolution · Battery Management · QFN3x3-16

ETA6005Q3Q from etasolution, in a QFN3x3-16. 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 SYS power_out System voltage pin and switching regulator output; connect an inductor and capacitor to form the output filter.
2 IN power_in Input pin that can connect to an AC adaptor or USB charger output (4.4V to 5.5V input range); bypass with a 10uF capacitor each to GND and PGND.
3 SW output Switching node of the switching regulator; connect a 1uH to 2.2uH inductor from this pin to SYS.
4 SW output Switching node of the switching regulator; connect a 1uH to 2.2uH inductor from this pin to SYS.
5 PGND power_in Power ground; bypass with a 10uF capacitor to IN with the shortest possible trace.
6 ENB input Active-low enable; tie low to enable charging, tie high to disable charging while keeping the power path from BATT to SYS (logic high min 1.6V, logic low max 0.3V).
7 NTC input Thermistor input for battery temperature monitoring.
8 GND power_in Analog ground pin; bypass with a 10uF capacitor to IN.
9 STAT output Open-drain charging status indication pin capable of driving 10mA (0.2V output low at 10mA).
10 GND power_in Analog ground pin; bypass with a 10uF capacitor to IN.
11 ISET1 passive AC fast-charge current set pin; a resistor to GND sets the charge current when USB_DET is low (Icharge = 1V*1000/RISET1).
12 ISET2 passive USB charge current set pin; a resistor to GND sets the charge current when USB_DET is high (Icharge = 1V*1000/RISET2).
13 USB_DET input Charge current select input; low selects AC fast-charge current set by ISET1, high selects USB charge current set by ISET2, default low.
14 BATT bidirectional Battery pin; connect a battery to this pin (termination voltage 4.35V typical).
15 SYS power_out System voltage pin and switching regulator output; connect an inductor and capacitor to form the output filter.
16 BATT bidirectional Battery pin; connect a battery to this pin (termination voltage 4.35V typical).
17 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
