Functional Description
The MIC834 monitors the input voltage and detects when it
is higher than a programmed level (plus V
HYST). This condi-
tion asserts the active-high output. An external pull-up resis-
tor is used to produce a logic-one output. When the input
voltage falls below the programmed threshold (V
INP <VREF),
the output stage is on.
Voltage Low Output
The voltage-low output (OUT) is an active-high, open-drain
output which sinks current when the MIC834 detects a low
input voltage.

Trip Points
Input voltage is monitored by a comparator via a voltage
divider network. The divided voltage is compared to an
internal reference voltage. When the voltage at the input pin
INP exceeds the internal reference voltage (plus V
HYST), the
output is pulled high by an external resistor.
V
HYST is typically 23mV, and is added to the programmed
threshold voltage for positive-going inputs. Decreasing in-
puts trip at the user-programmed threshold voltage.
The tolerance of the switching threshold on the falling edge
is equal to the tolerance of just the voltage reference. The
tolerance of the switching threshold on the rising edge is
equal to the tolerance of the voltage reference
plus the
tolerance of the hysteresis voltage.
