TPS3700 Over/Under V Supervisor Eval Kit

TPS3700 Window Comparator Evaluation Kit

A Texas Instruments evaluation module allowing design engineers to assess the performance of the TPS3700 high voltage window comparator for over- and under-voltage detection. This supervisory application features wide supply voltage range, very low quiescent current and high accuracy with two independent open-drain outputs. Headers on the PCB permit easy connection to external test and application circuitry.

Comparators, Texas Instruments

Texas Instruments’ range of voltage comparators includes not only conventional single, dual and quad comparator packages but also window comparators and over- & under-voltage supervisors.

Although comparators and operational amplifiers are superficially similar devices their operation in practical applications is very different. Op amps are intended for linear operation accompanied by suitable feedback whereas comparators are tailored for rapid switching and generally operated in open-loop mode. Dedicated voltage comparators have significantly shorter propagation delays and are capable of faster response times under saturated conditions. Most comparators are also more tolerant of high differential input voltages and many have open-collector outputs allowing parallel operation with other devices.
