DESCRIPTION
Regulated 5V output. Used to pull-up user programmable inputs IGQ0, IGQ1, BATT-ON, A1, A0, and WP (if
needed).
Address Select Input. It has an internal pulldown resistor. (>10MΩ typical)
The A0 and A1 bits allow for up to 4 X80000 devices to be used on the same SMBus serial interface.
V4 Voltage Good Output. This open drain output goes LOW when EN4 is less than V_TRIP4 and goes HIGH when
EN4 is greater than V_TRIP4. There is a user selectable delay circuitry on this pin.
V4 Voltage Enable Input. Fourth voltage enable pin. If unused connect to V_RGO.
V3 Voltage Good Output (Active Low). This open drain output goes LOW when EN3 is less than V_TRIP3 and
goes HIGH when EN3 is greater than V_TRIP3. There is a user selectable delay circuitry on this pin.
V3 Voltage Enable Input. Third voltage enable pin. If unused connect to V_RGO.
V2 Voltage Good Output (Active Low). This open drain output goes LOW when EN2 is less than V_TRIP2 and
goes HIGH when EN2 is greater than V_TRIP2. There is a user selectable delay circuitry on this pin.
V2 Voltage Enable Input. Second voltage enable pin. If unused connect to V_RGO.
Positive Supply Voltage Input.
Negative Supply Voltage Input.
Analog Undervoltage and Overvoltage Input. Turns off the external N-channel MOSFET when there is an
undervoltage or overvoltage condition.
Circuit Breaker Sense Input. This input pin detects the overcurrent condition.
Gate Drive Output. Gate drive output for the external N-channel MOSFET.
Drain. Drain sense input of the external N-channel MOSFET.
Not Available. Do not connect to this pin.
Address Select Input. It has an internal pulldown resistor. (>10MΩ typical)
The A0 and A1 bits allow for up to 4 X80000 devices to be used on the same SMBus serial interface.
Serial Data. SDA is a bidirectional pin used to transfer data into and out of the device. It has an open drain output
and may be wire ORed with other open drain or open collector outputs. This pin requires a pull up resistor and the
input buffer is always active (not gated).
Serial Clock. The Serial Clock controls the serial bus timing for data input and output.
V1 Voltage Enable Input. First voltage enable pin. If unused connect to V_RGO.
