MAX16143/MAX16145/ High-Voltage Supervisors with Manual Reset MAX16147/MAX16149 Input General Description Benefits and Features The MAX16143, MAX16145, MAX16147, and MAX16149 Factory-Set Reset Threshold Options from +3.3V to are supervisory circuits that monitor their own supply volt- +11.6V ages using a factory-set reset threshold that ranges from Manual Reset Input +3.3V to +11.6V. A manual reset (MR or MR) input is in- Active-High and Active-Low Trigger Options cluded. The RESET (or RESET) output has options for ac- Optional Internal Pullup or Pulldown tive-low, active-high, push-pull, or open-drain. The reset Fast (45s) and Slow (50ms) Debounce Time output asserts when the monitored voltage falls below the Options threshold voltage, and remains asserted until the moni- Guaranteed Reset Valid to V 1.3V CC tored voltage has exceeded its threshold (plus hysteresis) Push-Pull and Open-Drain Reset Output Options for a time equal to the factory-set reset timeout period. MAX16143: Open-Drain, Active-Low Available reset timeout periods range from 30s to 4.2s. MAX16145: Open-Drain, Active-High The 5-pin SOT23 and 4-bump wafer-level packages MAX16147: Push-Pull, Active-Low (WLPs) offer compatibility with space-constrained environ- MAX16149: Push-Pull, Active-High ments.

Note that a +, , or - in the package code indicates RoHS status only. Package drawings may show a different suffix character, but the drawing pertains to the package regardless of RoHS status. Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board.
