FS210/FS310 Datasheet

Typical Application Circuit

A schematic representation of a typical application circuit is shown below, one each for the FS210 and FS310. In this circuit,

the device is configured for master-mode power-up sequences: the MODE pin is pulled high, and a M24C32 non-volatile

EEPROM device is placed on the same I2C bus. This circuit would be most appropriate for a system design in which there is

no microcontroller with an I2C port in the system to store configuration data and load them into the device upon power-up

in the field. If such a microcontroller is available in the system, the MODE pin of the device would be pulled low, the

M24C32 device would be absent, and the I2C bus lines (SCL, SDA) would be brought out to connect to the I2C port of the

microcontroller. The typical application circuit contains a visible LED in series with a current-limiting resistor connected to

the open-drain IRQZ pin of the device to produce a visible indication of an alarm condition.
