Change of Detectable Voltage

If the required voltage is not found in

the standard product selection table, it

is possible to change it by using

external resistance dividers or diodes.

Varying the detectable voltage with a

resistance divider

Varying the detectable voltage with a

diode

Malfunction Analysis

The following circuit demonstrates the

way a circuit analyzes malfunctions by

monitoring the variation or spike noise

of power supply voltage.

Charge Monitoring Circuit

The following circuit shows a charged

monitor for protection against battery

deterioration by overcharging. When

the voltage of the battery is higher than

the

set

detectable

voltage,

the

transistor turns onto bypass the charge

current, protecting the battery from

overcharging.

Level Selector

The following diagram illustrates a logic level selector.
