RENESAS · Monitors & Reset Circuits · MSOP-10

ISL28022FUZ from RENESAS, in a MSOP-10. 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 slave address select bit 1; it has four selectable levels (VCC, GND, SCL/SMBCLK, SDA/SMBDAT) and is one of two address pins giving 16 address combinations.
2 A0 input I2C/SMBus slave address select bit 0; it has four selectable levels (VCC, GND, SCL/SMBCLK, SDA/SMBDAT) and is one of two address pins giving 16 address combinations.
3 EXT_CLK/INT bidirectional External ADC clock input or CPU interrupt output; when configured as an interrupt it is an open-drain output that 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 (SMBCLK is the SMBus equivalent).
6 VCC power_in Positive supply pin for the analog circuitry; the chip supply operates from 3V to 5.5V.
7 GND power_in Negative power pin that can be connected to ground or to a negative voltage; all internal voltages are referenced to it.
8 VBUS power_in Bus voltage sense input for the supply being monitored, with a measurable range of 0V to 60V.
9 VINM input Current sense minus input; connects to the most negative side of the shunt resistor.
10 VINP input Current sense plus input; connects to the most positive side of the shunt resistor.
