General Description

The MIC2786/MIC2787 are low-current, ultra-small, push button supervisor reset ICs with an integrated supply voltage monitor. The device features two manual reset inputs and two reset outputs. The reset outputs are asserted and held when the supply voltage decreases below the factory programmed threshold voltage. Reset will be asserted for the reset timeout delay once the supply voltage increases above the rising threshold voltage or when both manual reset inputs are asserted low for longer than the setup delay time.

特性 Features

• 1.6V to 5.5V operating voltage

• 7.4µA supply current when /MR0, /MR1 not asserted

• 1.66V to 4.63V preset voltage threshold options

• 2.5 voltage threshold accuracy over temperature

• Asserting /MR0 and /MR1 for the setup delay time asserts reset output for the reset timeout delay

• Programmable delay (PDY) input selects 2s, 4s or 6s setup delay

• Factory-programmed 140ms (min.) or 240ms (min.) reset timeout delay

• Integrated /MR0, /MR1 pull-up resistors (MIC2786)

•Dual reset outputs:

− Open-drain, active-low reset output (/RST)

− Push-pull, active-high reset output (RSTP)

• −40°C to +85°C ambient operating temperature range

• 8-pin 2mm x 2mm x 0.55mm Thin MLF® package

Applications

•Smart phones

•Tablets

• Set-top boxes (STB)
