Description
General-purpose I/O pin that can be configured as digital inputs or outputs.
General-purpose I/O pin that can be configured as digital inputs or outputs.
Fan tachometer input with internal 10 kΩ pull-up resistor to 3.3 V STBY. Can be
reconfigured as a general-purpose, open drain, digital I/O pin.
Fan tachometer input with internal 10 kΩ pull-up resistor to 3.3 V STBY. Can be
reconfigured as a general-purpose, open drain, digital I/O pin.
Fan tachometer input with internal 10 kΩ pull-up resistor to 3.3 V STBY. Can be
reconfigured as a general-purpose, open drain, digital I/O pin.
Fan tachometer input with internal 10 kΩ pull-up resistor to 3.3 V STBY. Can be
reconfigured as a general-purpose, open drain, digital I/O pin.
Monitors the main 3.3 V system supply. Does not power the device.
Ground pin for digital circuits.
Fan tachometer input with internal 10 kΩ pull-up resistor to 3.3 V STBY. Can be
reconfigured as a general-purpose, open drain, digital I/O pin.
Fan tachometer input with internal 10 kΩ pull-up resistor to 3.3 V STBY. Can be
reconfigured as a general-purpose, open drain, digital I/O pin.
Fan tachometer input with internal 10 kΩ pull-up resistor to 3.3 V STBY. Can be
reconfigured as a general-purpose, open drain, digital I/O pin.
Fan tachometer input with internal 10 kΩ pull-up resistor to 3.3 V STBY. Can be
reconfigured as a general-purpose, open drain, digital I/O pin.
Open Drain Serial Bus Clock. Requires a 2.2 kΩ pull-up resistor.
Serial Bus Data. Open drain I/O. Requires a 2.2 kΩ pull-up resistor.
This is a three-state input that controls the two LSBs of the serial bus address. It also
functions as the output for NAND tree testing.
An active high input that captures a chassis intrusion event in Bit 6 of Status Register 4.
This bit remains set until cleared, as long as battery voltage is applied to the VBAT input,
even when the ADM1026 is powered off.
Interrupt Request (Open Drain). The output is enabled when Bit 1 of the configuration
register is set to 1. The default state is disabled. It has an on-chip 100 kΩ pull-up resistor.
