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

This device is ideal to use in battery-powered or microprocessor based systems and can be used as a low voltage indicator or reset circuit.

8.2 Typical Application

8.2.1 Design Requirements

For this design example, use the parameters listed in Table 1 as the input parameters.

Table 1. Design Parameters

PARAMETER EXAMPLE VALUE
Input supply voltage maximum 7 V
VOUT maximum 7 V
VOUT minimum 0 V
Pullup resistor 470 kΩ

8.2.2 Detailed Design Procedure

The LMS33460 is a very easy to use low voltage detector. All that required is the input supply voltage and a pullup resistor at the output. TI recommends 470 kΩ for the pullup resistor.

8.2.3 Application Curve

RL = 475 kΩ
