8 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

8.1 Application Information

The TMP821 device needs very few external components for the features described in Feature Description. The

device needs a 1-µF or more capacitor connected at VCC. The Lock Detection capacitor decides the hiccup

time.

8.2 Typical Application

Figure 5. Typical Application Circuit

8.2.1 Design Requirements

For this design example, use the following parameters:

•

Test setup input voltage: 12-V DC source

•

VCC capacitor: 1 µF or more

•

H Bridge top side: P-channel FETs

•

H Bridge bottom side: N-channel FETs
