DS1632 Datasheet, PDF (6/6 Pages) Dallas Semiconductor – PC Power-Fail and Reset Controller

TIMING DIAGRAM: POWER-UP
DS1632
NOTES:
1. All voltages are referenced to ground.
2. Measured with outputs open.
3. The PBRST input has an internal pull-up of 10kW to V_CC.
4. Supply current output is specified with 0.3V drop from V_BAT or V_CC.
5. RST , PF , and LB are open-drain outputs.
6. RST and PF remain within 0.5 volts of V_CC on power down until V_CC drops below 2.0V.
7. Sink and source currents apply to all outputs except OSC OUT which has a drive capability of
sourcing 500 mA at V_OH = V_CCO - 0.5V and sinking 1 mA at V_OL = 0.5 V.
