IP6520_20W

INJOINIC · Battery Management · ESOP-8

IP6520_20W from INJOINIC, in a ESOP-8. 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 VOUT input Output voltage feedback pin for the buck converter, with the output range stated as 3 V to 12 V; C5 should be placed close to this pin.
2 VIN power_in Input voltage pin with a recommended range of 7.1 V to 32 V (absolute maximum -0.3 V to 40 V), and the input filter capacitor must be placed close to the IC.
3 SW output DC-DC switching node that connects to the inductor; LX voltage is limited to -0.3 V to VIN+0.3 V, and the R1/C6 RC snubber should be placed close to this pin.
4 BST passive Bootstrap pin that provides the high-side gate drive voltage; the bootstrap capacitor must be placed right next to the BST and SW pins, and the datasheet gives no separate voltage limit for this pin.
5 DM bidirectional USB fast-charge identification signal DM, with an absolute maximum of -0.3 V to 6 V and DP/DM overvoltage protection that trips at 4.5 V typical.
6 DP bidirectional USB fast-charge identification signal DP, with an absolute maximum of -0.3 V to 6 V and DP/DM overvoltage protection that trips at 4.5 V typical.
7 CC1 bidirectional Type-C detection pin CC1, with an absolute maximum of -0.3 V to 30 V and a CC overvoltage protection threshold of 6.0 V typical.
8 CC2 bidirectional Type-C detection pin CC2, with an absolute maximum of -0.3 V to 30 V and a CC overvoltage protection threshold of 6.0 V typical.
9 GND power_in Exposed pad (EPAD) that serves as both power and thermal ground and must make good contact with the PCB ground.
