INTRODUCTION

OPERATION

TelCom's TC54 series of voltage detectors are de-

signedtosupersedeavarietyofdiscretecomparatorcircuits

and bipolar technology voltage detectors.

The TC54VN equivalent circuit is shown in Figure 1.

The internal precision temperature-compensated reference

and comparator circuit consistently monitor V_INfor an under-

voltagecondition. Whensuchaconditionoccurs, theoutput

isforcedtotheactive(LOW)stateandremainsthereuntilV_IN

is once again within tolerance. As shown in the timing

diagram of Figure 1, the output is forced active when V_IN<

(–V_DET) (Where (–V_DET) is the threshold voltage) and returns

HIGH when V_INexceeds (–V_DET) plus 5% hysteresis (ex-

ample: if (–V_DET) = 2.0V, the output will go HIGH when V_IN>

2.1V).

These voltage detectors are especially suited for appli-

cation in battery powered systems because of their ex-

tremely low 1µA operating current. Each part is laser

programmed to the desired trip point voltage over the range

of 0.8V 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-23 and SOT-89 or through-hole TO-92 types.

TC54 AS A MICROPROCESSOR RESET

GENERATOR

Following a power outage, microprocessors require a

reset to get them back into their starting state. Commonly

used simple Schmitt trigger/capacitor circuits are inad-

equate 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 standard TC54 and external RC time

constant, replacing bipolar integrated voltage detectors

(see Table 1).
