ASM161/ASM162
Valid Reset with VCC under 1.1V
Application Information
To ensure that logic inputs connected to the ASM162
RESET pin are in a known state when VCC is under 1.1V,
a 100kΩ pull-down resistor at RESET is needed. The
Glitch Resistance
The ASM161/162 are relatively immune to short duration
negative-going VCC transients/glitches. A VCC transient
that goes 100mV below the reset threshold and lasts 20s
or less will not typically cause a reset pulse.
value is not critical.
This scheme does not work with the open-drain outputs
of ASM161.
