It monitors up to three supply rails and drives a push-pull, active-low reset output when any monitored voltage falls outside its programmed threshold. The part offers nine selectable threshold combinations, which lets you set undervoltage levels without external resistor dividers — a clean BOM play for multi-rail boards. The reset timeout is fixed at 140 ms by default but can be adjusted with an external capacitor, giving you control over power-up sequencing delays. The operating temperature range spans -40°C to 125°C, so it fits industrial motor drives, base-station power controllers, and automotive body electronics where the ambient can climb. ## What the ratings mean for the BOM Three monitored voltages cover the typical core, I/O, and auxiliary rails on a mixed-signal board. The nine selectable threshold combinations map to common supply levels via a logic input, no resistor network. The push-pull output sinks and sources current, so it drives the reset line of an MCU or FPGA directly without a pull-up resistor. Active-low polarity matches the convention on most processors and CPLDs. The 140 ms timeout gives the bulk supply capacitors time to charge before the system starts; if your load needs a longer wait, the adjustable option buys that margin with one capacitor. Surface-mount 20-TQFN (4x4 mm) with an exposed pad pulls heat into the PCB ground plane. For a sequencer drawing microamps of quiescent current, thermal derating is not a concern, but the pad does improve solder-joint reliability under vibration. ## Lifecycle and sourcing reality The MAX16028TP+ carries an active lifecycle status and is ROHS3 compliant. For a BOM freeze or a high-reliability program, this part is a safe anchor; you are not chasing obsolete stock.","metaTitle":"MAX16028TP+ Sequencer, 3-Channel Supervisor, 20-TQFN","metaDescription":"MAX16028TP+ 3-channel voltage sequencer with 9 selectable thresholds, active-low reset, 140ms timeout, -40°C to 125°C.
