FUNCTION
Push-Pull Output Clock. This clock changes between two programmable frequencies based on state
of power good. High impedance when disabled and when ENABLE is low.
Active-Low, Open-Drain Fault Output for Remote Diode Temperature Sensor Connected to ADC5
Active-Low, Open-Drain Fault Output for Remote Diode Temperature Sensor Connected to ADC4
Power-Good Output for ADC3. Active-high push-pull or open-drain output.
Regulator for Low-Voltage Digital Circuitry. Bypass REG18 to V SS with 1 F F and 10nF capacitors. Do
not connect other circuitry to this pin.
Active-Low, Open-Drain Fault Output for Voltage or Current Fault on ADC3
Power-Good Output for ADC2. Active-high push-pull or open-drain output.
Active-Low, Open-Drain Fault Output for Voltage or Current Fault on ADC2
Power-Good Output for ADC1. Active-high push-pull or open-drain output.
Active-Low, Open-Drain Fault Output for Voltage or Current Fault on ADC1
Power-Good Output for ADC0. Active-high push-pull or open-drain output.
Regulator for Analog Circuitry. Bypass REG25 to V SS with 30 F F to 47 F F with an ESR of 0 W to
500m W . Do not connect other circuitry to this pin.
Active-Low, Open-Drain Fault Output for Voltage or Current Fault on ADC0
I 2 C/SMBus-Compatible Bidirectional Data Line. Open-drain output.
I 2 C/SMBus-Compatible Clock
I 2 C/SMBus Address Select Bit 0
Active-Low Force Nonvolatile Logging. Active-low input with an internal 55 F A pullup. A falling edge on
this pin causes the device to log the most recent set of collected data into the nonvolatile memory. This
pin has a 100 F s deglitch filter. Leave open circuit if not needed.
Device Enable. Connect to V DD to enable the device. This pin has a 100 F s deglitch filter. When low,
no monitoring or data logging occurs, the PGn outputs are forced low, and the FAULTn outputs are
high impedance. On the falling edge of ENABLE, the device attempts to write MFR_TIME_COUNT
into nonvolatile memory.
I 2 C/SMBus Address Select Bit 1
Ground Reference for ADC5 Remote Thermal Diode Voltage Measurement
Remote Thermal Diode ADC5 Sense Input, Measurement Relative to RS-5
Exposed Pad (Bottom Side of Package). Connect EP to V SS .
Note: All pins except V DD , V SS , REG18, REG25, the ADC pins, and the exposed pad are high impedance with a 55μA pullup dur-
ing device power-up and reset. After device reset, the weak pullup is removed and the pin is configured as an input or output.
