Choose R2 to have a resistance of up to 500kΩ.
Calculate R1 by:
The MAX6763/MAX6764 provide inputs to a window
detector allowing the programming of the threshold
voltage to within V
Choose R1, R2, and R3 such that:
The MAX6754–MAX6762 allow the setting of the window
voltage range of the voltage detector. Connect SET to
GND to set a ±5% window. Connect SET to V
±10% window. Bias SET to V
The MAX6754–MAX6762 include an active-low manual
reset input. Drive MR low to assert a reset output
(MAX6754/MAX6755/MAX6756) or an undervoltage
output (MAX6757/MAX6758/MAX6759). The output
remains asserted for the specified propagation delay
time (see Figure 7) after MR goes high. MR is internally
pulled to V
