概述

TPK1034 is a low voltage four-channel power monitor and sequencer. The power supply range is 2 V to 5.5 V, while if the shunt reference is enabled, the TPK1034 can sustain up to 22 V supply voltage. Each channel has an independent and adjustable threshold that can monitor voltage down to 0.98 V. If the monitored voltage falls below the threshold, the corresponding output is low. If the monitored voltage rises above the threshold, the output turns high after a capacitor-set delay time, the channel output is open-drain configuration.

With the power monitor function, the TPK1034 can achieve power sequencing control, and the capacitor of each channel can adjust the sequencing timing.

TPK1034 has an overall enable control for all channel outputs. When overall enable is active, each channel can be controlled by the corresponding enable. The overall enable control can disable all channel outputs by turning channel output low in a fixed sequence from channel 4 to channel 3, then channel 2 and channel 1. There is a delay time before each channel outputs low, which can be adjustable by another capacitor.

TPK1034 also includes a power good indication with opendrain active high to indicate all channels output high.
