Adjustable Hysteresis in Microprocessor-Reset ICs

By: Eric Schlaepfer

摘要 : The amount of hysteresis needed in an application can vary and depends on many factors. This simple circuit lets you adjust the otherwise fixed hysteresis (the voltage difference between rising and falling thresholds on VCC) that governs the operation of a 3-pin microprocessor-reset IC.
