Package Type

General Description:

The TC53 is a low-power voltage detector. Typical

supply current consumption is only 1A at an input

volt age of 2V. The volta ge detection threshold se tting is

factory-programmed and ensured to ±2% accuracy.

Threshold settings are available over a range of 1.6V

to 6.0V. The TC53 has both complementary (CMOS)

and open drain (NMOS) output configuration options.

TC53 is the ideal voltage detector for precision

applic ations in whic h small s ize, low inst alled c ost, hig h

accuracy and low supply current consumption are

critical.

Note 1: An additional resistor between the VIN pin and the supply voltage may alter the electrical characteristics due to the increasing values of

VDR.

2: The power consumption during power-start to output being stable (release operation) is 2A greater than it is after that period

(completion of release operation) because of rush current in the delay circuit.

3: VT is the factory-programmed voltage detection threshold.

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 it s family of products is one of the most secure families of its kind on the market today, when used i n 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 c onstantly evolving. We a t Microc hip are co m mitted to continuously improving the code prot ect ion featur es 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.

Microchip received ISO/TS-16949:2009 certification for its worldwide

headquarters, design and wafer fabrication facilities in Chandler and

Tempe, Arizona; Gresham, Oregon and design centers in California

and India. The Company’s quality system processes and procedures

are for its PIC® MCUs and d sPIC® DSCs, KEELOQ® code hopping

devices, Serial EEPROMs, microperiph erals, nonvolatile memory and

analog products. In addition, Microchip’s quality system for the design

and manufacture of development systems is ISO 9001:2000 certified.
