POWER-ON MANAGEMENT FOR VOLTAGE DOWN-CONVERTER |
摘要 |
A power-on management system (80) for an on-chip voltage down-converter (79), monitoring both external (Vcc_EXT) and internal (Vcc_INT) voltage supplies to independently determine (81, 82) when both supplies have reached minimum levels for proper operation of on-chip circuitry. The power-on management system (80) supplies output signals that: control the discharge (DISCH_Vcc) of the internal supply nodes at the initiation of power-on; force the active mode (POW_ON = high) of the voltage down-converter; and deactivate a fast local voltage reference on completion of power-on (POW_ON = low). |
