Data Sheet

Consecutive Alerts

The EMC1403 and EMC1404 contain multiple consecutive alert counters. One set of counters applies

to the ALERT pin and the second set of counters applies to the THERM pin. Each temperature

measurement channel has a separate consecutive alert counter for each of the ALERT and THERM

pins. All counters are user programmable and determine the number of consecutive measurements

that a temperature channel(s) must be out-of-limit or reporting a diode fault before the corresponding

pin is asserted.

See Section 6.12 for more details on the consecutive alert function.

Digital Filter

To reduce the effect of noise and temperature spikes on the reported temperature, the External Diode

1 channel uses a programmable digital filter. This filter can be configured as Level 1, Level 2, or

Disabled. The typical filter performance is shown in Figure 5.3 and Figure 5.4.
