DESCRIPTION
Octal Positive/Negative
Voltage Monitor
The LTC2910 is an octal input voltage monitor intended
for monitoring multiple voltages in a variety of applica-
tions. Each input has a nominal 0.5V threshold, featuring
1.5% tight threshold accuracy over the entire operating
temperature range. Glitch ltering ensures reliable reset
operation without false or noisy triggering.
Polarity selection and a buffered reference allow monitor-
ing up to two separate negative voltages. A three state
input pin allows setting the polarity of two inputs without
requiring any external components.
The LTC2910 provides a precise, versatile, space-con-
scious, micropower solution for voltage monitoring.
