AS1925

The AS1925/AS1926 microprocessor supervisory cir-cuits were designed to assert a single reset if the moni-tored supply voltage drops below its reset threshold or if the manual reset is activated. The reset remains asserted for a fixed timeout delay after VCC has risen above the reset threshold and the manual reset is deas-serted.

Their small size, excellent circuit reliability, and low sup-ply current (3.5 A) make the AS1925/AS1926 a very low cost solution by eliminating external components and adjustments when used with low-voltage (+0.9 to +1.5V) systems.

AS1925 are available as the following standard products:

The active-low open-drain reset output requires a pullup resistor AS1925 that can be connected to a voltage from 0 to VCC. The reset comparator was specifically designed to ignore fast VCC transients.

v are available in a 5-pin SOT23 package.
