UCD9080 General Description

The UCD9080 Power Supply Sequencer controls the enable sequence of up to 8 independent voltage rails and provides four general purpose digital outputs. The device operates from a 3.3-V supply, provides 3.2-mV resolution of voltage rails, and requires no external memory or clock. The UCD9080 monitors the voltage rails independently at more than a 20 kHz rate and has a high degree of rail sequence and rail error response configurability. The sequencing of rails can be based on timed events, or timed events in conjunction with other rails achieving regulation or a voltage threshold. In addition, each rail is monitored for undervoltage and overvoltage glitches and thresholds. Each rail the UCD9080 monitors canbe configured to shutdown a user-defined set of other rails, and alarm conditions are monitored on aper-rail basis.

UCD9080 Maximum Ratings

  VALUE UNIT
Voltage applied at VCC to VSS 0.3 to 4.1 V
Voltage applied to any pin(2) 0.3 to VCC + 0.3 V
Diode current at any device terminal ±2 mA
Tstg Storage temperature 40 to 85 °C


(1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltages referenced to VSS.
