IW657P-30-72

Dialog Semiconductor · Monitors & Reset Circuits · TDFN-14(3x4)

IW657P-30-72 from Dialog Semiconductor, in a TDFN-14(3x4). 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 DIS output Discharging circuit used for fast discharging of the output capacitor (absolute maximum -0.3 to 30 V, peak 600 mA at VDIS=12V).
2 DRV output External circuit drive that can drive an optocoupler LED with automatic current limiting for transmitting signals to the primary side (absolute maximum -0.3 to 30 V).
3 VCC power_in IC power supply (absolute maximum -0.3 to 30 V).
4 DET input AC unplug detect input (absolute maximum -0.7 to 30 V).
5 VBUS power_in Monitors the VBUS voltage after the N-FET switch (absolute maximum -0.7 to 30 V at IVBUS < 10mA).
6 VBUS_G bidirectional Connects to the external N-FET gate pin for gate-source voltage control (absolute maximum -0.7 to 35 V).
7 CC2 bidirectional Configuration Channel 2 (absolute maximum -0.3 to 30 V, with over-voltage protection).
8 CC1 bidirectional Configuration Channel 1 (absolute maximum -0.3 to 30 V, with over-voltage protection).
9 IS- input Output current sensing terminal minus for the current sensing resistor (absolute maximum -0.3 to 7 V).
10 IS+ input Output current sensing terminal plus for the current sensing resistor (absolute maximum -0.3 to 7 V).
11 SD bidirectional Connects to an external NTC resistor to measure the power adapter temperature (absolute maximum -0.3 to 7 V).
12 D- bidirectional USB D- signal with over-voltage protection (absolute maximum -0.3 to 7 V).
13 GND power_in Ground.
14 D+ bidirectional USB D+ signal with over-voltage protection (absolute maximum -0.3 to 7 V).
15 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
