  台湾致新 G697L293T1Uf SOT-23-5 微处理器复位集成电路

  General Description

  The G696/G697 are microprocessor (μP) supervisory

  circuits used to monitor the power supplies in μP and

  digital systems. They provide excellent circuit reliability

  and low cost and adjustments when used with +5V,

  +3.3V, +3.0V- powered circuits.

  These circuits perform a single function: they assert a

  reset signal whenever the VCC supply voltage declines

  below a preset threshold, with hysteresis keeping it

  asserted for time delay determined by externally programmable

  time delay generator after VCC has risen

  above the reset threshold. Reset thresholds suitable

  for operation with a variety of supply voltages are

  available.

  The G697L has an open-drain output stage, while the

  G696 have push-pull outputs. The G697L’s open-drain

  RESET output requires a pull-up resistor that can be

  connected to a voltage higher than VCC. The G696L

  have an active-low RESET output, while the G696H

  has an active-high RESET output. The reset comparator

  is designed to ignore fast transients on VCC,

  and the outputs are guaranteed to be in the correct

  logic state for VCC down to 0.8V.

  Low supply current makes the G696/G697 ideal for

  use in portable equipment. The G696/G697 are available

  in 5-pin SOT23-5 or TSOT-23-5 packages.
