• Manufacturer Part Number: MAX6326-22W
• Description: 3-pin ultra-low power SC70/SOT microprocessor reset circuit
• Manufacturer: PHILIPS [NXP Semiconductors]

They assert a reset signal when the V
preset reset threshold voltage. The reset signal remains asserted for
Philips Semiconductors
DESCRIPTION
The MAX6326/MAX6327//MAX6328/MAX6346/MAX6347/MAX6348
microprocessor ( P) reset circuits monitor power supplies in P and
digital systems. These devices eliminate external components and
adjustments while providing excellent circuit reliability and low cost
solution. They are used to monitor 2.5 V, 3 V, 3.3 V and 5 V power
supplies.
at least 100 ms after the V
reset threshold are factory trimmable from 2.2 V to 4.63 V in
approximately 100 mV increments. All these parts are guaranteed to
assert a reset for V
fast transients on V
The devices vary in their output configuration. The
MAX6326/MAX6346 have push-pull, active-LOW reset output; while
the MAX6328/MAX6348 have open drain, active-LOW reset output.
The MAX6327/MAX6347 have push-pull, active HIGH reset output.
The lower threshold MAX6326/MAX6327/MAX6328 have ultra-low
supply current of typically 0.5 A making them ideal for battery
powered applications. All six devices are available in both the 3-pin
SOT23 and SC70 packages.
