ASM161/ASM162

Application Information

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.

Valid Reset with VCC under 1.1V

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

value is not critical.

This scheme does not work with the open-drain outputs

of ASM161.
