Low Power Comparators

ST offers the most efficient low-power comparators on the market,  consuming as little as 220 nA per channel, in a variety of space-saving packages such as SOT-23 and SC-70, without sacrificing speed or precision.

These attributes allow application designers to extend battery life without loss of performance,  in applications where board space is at a premium.

TS33 voltage comparator

The TS33 line consumes one third the current for the same response time, compared with currently available devices such as the LMV331. ST’s latest voltage comparator addresses the demand for greater power efficiency and longer battery life in today’s portable electronics applications, in keeping with the Company’s ongoing commitment to sustainability. Available in single, dual and quad versions in space-saving SMD packages, ST’s ultra-low-power general-purpose voltage comparator targets signal-conditioning applications in mobile communications, battery-operated portable electronics, and alarm and security systems.

Nanopower comparators enabling high-performance and longer operating times with smaller batteries

TS88 line of single, dual and quad comparators with ultra-low current consumption.

The TS881 is a single comparator featuring an ultra-low supply current (210 nA typical with output high) with rail-to-rail input and output capability having a supply voltage range from 0.85 to 5.5 V.

Operating from a 1.1 to 5.5 V supply voltage, the TS882 and TS884, dual and quad comparators respectively, also feature an ultra-low supply current (220 nA typical per operator with output high) with rail-to-rail input and output capability.

These comparators keep the current consumption at an ultra-low level over a wide temperature range (-40 to +125 °C).

The TS881 is available in SC70-5 and SOT23-5 packages, the TS882 in MiniSO8 and DFN8 2 x 2 mm packages and the TS884 in a QFN16 3 x 3 mm package, providing great space-saving on your PCB.

Designed to minimize battery supply leakage, the TS88 line of comparators enhance battery lifetime and their performance makes them perfect for use in a wide range of portable applications.
