ISL28022FRZ-T

RENESAS · Supervisor And Reset ICs · QFN-16(3x3)

ISL28022FRZ-T from RENESAS, in a QFN-16(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 A1 input I2C/SMBus address select bit 1, one of two address-select pins with four selectable levels (VCC, GND, SCL/SMBCLK, SDA/SMBDAT) for 16 address combinations.
2 A0 input I2C/SMBus address select bit 0, one of two address-select pins with four selectable levels (VCC, GND, SCL/SMBCLK, SDA/SMBDAT) for 16 address combinations.
3 EXT_CLK/INT bidirectional External ADC clock input or CPU interrupt output; when configured as an interrupt the output is open drain and requires a pull-up to a supply of up to 20V.
4 SDA/SMBDAT bidirectional I2C serial data input/output, an open-drain pin that requires a pull-up resistor connected to the device VCC.
5 SCL/SMBCLK input I2C serial clock input that clocks all data to and from the device.
6 NC unconnected No connect; no internal connection.
7 NC unconnected No connect; no internal connection.
8 NC unconnected No connect; no internal connection.
9 VCC power_in Positive supply pin for the analog circuitry, operating over a 3V to 5.5V chip supply range.
10 GND power_in Negative power pin that can be connected to ground or to a negative voltage (most negative supply in dual-supply applications).
11 VBUS power_in Bus voltage sense input, which should be connected to the supply bus to be monitored over a 0V to 60V range.
12 VINM input Current sense minus input, connected to the most negative side of the current shunt resistor.
13 VINP input Current sense plus input, connected to the most positive side of the current shunt resistor.
14 NC unconnected No connect; no internal connection.
15 NC unconnected No connect; no internal connection.
16 NC unconnected No connect; no internal connection.
17 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
