User’s Guide

Note the following details of the code protection feature on Microchip devices:

• Microchip products meet the specification contained in their particular Microchip Data Sheet.

• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions.

• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

• Microchip is willing to work with the customer who is concerned about the integrity of their code.

• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

EVALUATION BOARD USER’S GUIDE

Chapter 1. Product Overview

1.1 INTRODUCTION

This chapter provides an overview of the Voltage Supervisor SOT-23-5/6 Evaluation Board and covers the following topics:

• What is the Voltage Supervisor SOT-23-5/6 Evaluation Board?

• What the Voltage Supervisor SOT-23-5/6 Evaluation Board Kit includes

1.2 WHAT IS THE VOLTAGE SUPERVISOR SOT-23-5/6 EVALUATION BOARD?

The Voltage Supervisor SOT-23-5/6 Evaluation Board allows the system designer to quickly evaluate the operation of Microchip Technology’s voltage supervisors and voltage detectors in the SOT-23-5 (5-pin SOT-23) or SOT-23-6 (6-pin SOT-23) packages.

The Voltage Supervisor SOT-23-5/6 Evaluation Board Printed Circuit Board (PCB) supports the four different SOT-23-6 pinouts (which also supports compatible SOT-23-5 footprints) and one SOT-23-5 footprint.

The Voltage Supervisor SOT-23-5/6 Evaluation Board has been made generic so that other devices in the SOT-23-5 and SOT-23-6 packages may be supported with this board. Microchip device families supported include:

• Voltage Supervisors/Voltage Detectors

• Nonvolatile Digital Potentiometers (Digi-Pots)

• Operational Amplifiers (Op Amps)

• Comparators

• Low Drop-out Regulators (LDOs)

• Thermal sensors

• Analog-to-Digital Converters (ADCs)

• PFM/PWM Step-Down DC/DC Controllers

• Battery Charger Controllers

•PICmicro

1.3 WHAT THE VOLTAGE SUPERVISOR SOT-23-5/6 EVALUATION BOARD KIT

INCLUDES

This Voltage Supervisor SOT-23-5/6 Evaluation Board Kit includes:

• Five Voltage Supervisor SOT-23-5/6 Evaluation Board PCBs

• Three voltage supervisor device samples that can be installed on the Voltage Supervisor SOT-23-5/6 Evaluation Board PCBs

• Voltage Supervisor SOT-23-5/6 Evaluation Board User’s Guide (Electronic version on CD)

NOTES:

Chapter 2. Installation and Operation

2.1 INTRODUCTION

The blank Printed Circuit Board (PCB) allows the desired voltage supervisor/voltage detector device to be installed along with other desired passive components (resistors and capacitors) and connection posts.

The PCB supports four different SOT-23-6 and one SOT-23-5 pinouts. Two of these pinouts are used by the voltage supervisor/voltage detector product family, while the other pinouts are used by other Microchip analog and PICmicro products (see Appendix C. “Microchip SOT-23-5/6 Device Compatibility”). The PIC10F2XX devices uses the last pinout. This board is generic so that other devices may be supported. However, the silk-screen markings are designed for ease-of-use with the voltage supervisor devices.

2.2 FEATURES

The Voltage Supervisor SOT-23-5/6 Evaluation Board has the following features:

• Connection terminals may be either through-hole or surface-mount

• Four SOT-23-6 pinouts supported

- Also supports V

• One SOT-23-5 pinout supported

• Footprints for optional passive components for:

- Power supply filtering

- Device bypass capacitor

- Output filtering

- Output pull-up resistor

- Output pull-down resistor

- Output loading resistor

- Output series resistor

• Footprints for two optional switches for:

- Voltage supervisor manual resets

- PIC10F2XX general purpose inputs

• Silk screen area to write specifics of implemented circuit (on back of PCB), such as TC52 2.7V, 10 kΩ (to indicate that the device is the TC52 with the 2.7V trip point and an external 10 kΩ pull-up resistor on the output)

2.3 GETTING STARTED

The Voltage Supervisor SOT-23-5/6 Evaluation Board is a blank PCB that allows the user to configure the circuit to their exact requirements. The passive components use the surface-mount 805 package layout. Figure 2-1 shows the board circuit.

This evaluation board supports the following Microchip device families:

• Voltage Supervisors/Voltage Detectors

• Nonvolatile Digital Potentiometers (Digi-Pots)

• Operational Amplifiers (Op Amps)

• Comparators

• Low Drop-Out Regulators (LDOs)

• Thermal Sensors

• Aanalog-to-Digital Converters (ADCs)

• PFM/PWM Step-Down DC/DC Controllers

• Battery Charger Controllers

•PICmicro

Table 2-1 shows these product families, the devices that are supported and which SOT-23-5/6 layout option to use. Devices that are in a 5-pin SOT-23 package can be installed into the SOT-23-6 footprint.

Table 2-2 shows which circuit option needs to be used for a given voltage supervisor/voltage detector. There are currently no voltage supervisors/voltage detectors that use the option B, C or E pinout. For other Microchip analog devices, please refer to Appendix C. “Microchip SOT-23-5/6 Device Compatibility”.
