Response Time

Chart 3 - Typical Response Time vs. Cx; Vdd = 3.0

The QT113's response time is highly dependent

on burst length, which in turn is dependent on Cs

and Cx (see Charts 1, 2). With increasing Cs,

response time slows, while increasing levels of

Cs reduce response time. Chart 3 shows the

typical effects of Cs and Cx on response time.

HeartBeat™ Signal

The QT113's HeartBeat pulse works exactly the

same as in the QT110 except that the HeartBeat

rate is the same as the burst rate, which can vary

from 2ms to 100ms depending on Cs and Cx.

Detection methods for this health indicator

should take this into account. As with the QT110,

the HB signal can be suppressed if not wanted

by a variety of simple methods.
