Comparator with Hysteresis
Summary
Designing the simplest solution to a complex problem such as
fan/motor control on a system board can often be challenging.
Microchip has simplifi ed both the design and implementation of
such applications by introducing the new PIC12F609/HV609,
PIC12F615/HV615, PIC16F610/HV610 and PIC16F616/
HV616. The fi rst PIC microcontrollers of their kind, the 14-pin
PIC16F616 provide an increased feature set inclusive of an
enhanced full bridge Enhanced Capture/Compare Pulse Width
Modulation (ECCP), eight 10-bit ADC channels, 2 comparators
with selectable hysteresis, 4/8 MHz internal oscillator and 2K
words of Flash program memory. The 8-pin PIC12F615, provides
a half bridge ECCP , four 10-bit ADC channels, 1 comparator
with selectable hysteresis, 4/8 MHz internal oscillator and 1K
words of Flash program memory. The simplifi ed PIC16F610
and PIC12F609 provide similar features without the ADC
and ECCP . All of these PIC microcontrollers are available with
high voltage variants and provide an integrated shunt voltage
regulator allowing high voltage V
PIC12HV615, PIC16HV610 and PIC16HV616 provide the
ability to run as low as 2.0V, up to an unspecifi ed user-defi ned
maximum voltage. The shunt regulator is active when the

These high voltage variations are ideal for cost sensitive
applications with high voltage power rails.
suited for focused applications such as motor or fan control.
The comparator on all variants is steerable and designed with
greater hysteresis to provide the ability to use a Hall Effect
element for speed monitoring of a fan or motor. Due to the
differential signaling of the Hall Effect element, traditional
comparators do not always provide the ability to accurately
translate the varying frequency of the Hall Effect element into
a manageable digital signal. With the addition of hysteresis,
these newly designed comparators will in effect provide a trigger
window and ultimately greater ease in such translations. This,
paired with the integrated PWM, makes these products a robust
fan-control solution that is more cost effective and fl exible than
traditional dedicated fan control methods.
