Using the Microchip TC54 Voltage Detector

INTRODUCTION

Microchip's TC54 series of voltage detectors are designed to

supersede a variety of discrete comparator circuits and bipolar

technology voltage detectors.

These voltage detectors are especially suited for application in

battery powered systems because of their extremely low 1µA

operating current. Each part is laser programmed to the desired trip

point voltage over the range of 1.1V to 6.0V in 100mV steps. For

complete design flexibility, complementary or open-drain output

versions are available. TC54 package options include surface

mount SOT-23A and SOT-89 or through-hole TO-92 types.

OPERATION

The TC54 equivalent circuit is shown in Figure 1. The internal

precision temperature-compensated reference and comparator

circuit consistently monitor V

for an under-voltage condition.

When such a condition occurs, the output is forced to the active

(LOW) state and remains there until V

is once again within

tolerance. As shown in the timing diagram of Figure 1, the output

is forced active when V

< (–V

DET

) (Where (–V

DET

) is the threshold

voltage) and returns HIGH when V

exceeds (–V

DET

) plus 5%

hysteresis (example: if (–V

DET

) = 2.0V, the output will go HIGH

when V

> 2.1V).

TC54 AS A MICROCONTROLLER

RESET GENERATOR

Reset generators external to the microcontroller are necessary in

systems that have slowly rising power supplies. It is necessary to

hold the microcontroller in its reset state until the power supply has

reached a valid operating level. Commonly used simple Schmitt

trigger/capacitor circuits are inadequate since they do not

accurately monitor the power supply voltage tolerance. The TC54

series overcomes this problem with precise voltage detection.

Figure 2 shows a reset circuit using a TC54 replacing bipolar

integrated voltage detectors (see Table 1).
