Operating from just 0.85V to 5.5V with a typical supply current of only 210nA, it enables always-on monitoring circuits in battery-powered and energy-harvesting systems. The device features rail-to-rail input and output capability, built-in hysteresis for clean switching on slow-moving signals, and a propagation delay of 2\u03bcs with 100mV overdrive. Available in SOT-23-5 and SC70-5 packages, it is specified over the -40\u00b0C to +125\u00b0C temperature range with 8kV HBM ESD tolerance.","working_principle":"The TS881ILT operates as a single-ended voltage comparator with three functional blocks. (1) The rail-to-rail input stage uses complementary P-channel and N-channel differential pairs to maintain valid common-mode operation across the entire supply voltage range from ground to VCC. Internal hysteresis of approximately 2.4mV creates two threshold levels that prevent output oscillation on slowly varying or noisy input signals. (2) The high-gain amplification stage provides sufficient voltage gain to convert small input differentials into full logic-level output swings while consuming minimal current. The ultra-low 210nA supply current is achieved through careful bias optimization. (3) The push-pull output stage drives rail-to-rail output voltages without requiring an external pull-up resistor, sourcing and sinking current directly into the load.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>OUT<\/td><td>Push-pull output (rail-to-rail)<\/td><\/tr><tr><td>2<\/td><td>V-<\/td><td>Negative supply \/ Ground<\/td><\/tr><tr><td>3<\/td><td>+IN<\/td><td>Non-inverting input<\/td><\/tr><tr><td>4<\/td><td>-IN<\/td><td>Inverting input<\/td><\/tr><tr><td>5<\/td><td>V+<\/td><td>Positive supply (0.85-5.5V)<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Battery voltage monitoring with sub-microamp current draw for years of operation<\/li><li>Energy harvesting system wake-up threshold detection with 0.85V minimum operation<\/li><li>Portable medical device alarm and limit comparators requiring minimal power<\/li><li>Sensor signal threshold detection in wireless IoT nodes<\/li><li>Power-on reset and undervoltage lockout in ultra-low-power systems<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Difference<\/th><\/tr><tr><td>TS881IQ5T<\/td><td>STMicroelectronics<\/td><td>SC70-5 package option<\/td><\/tr><tr><td>TS9002<\/td><td>Silicon Labs<\/td><td>Dual nanopower comparator<\/td><\/tr><tr><td>MAX9025<\/td><td>Maxim<\/td><td>Nanopower comparator, SOT-23-5<\/td><\/tr><tr><td>TLV3491AIDBVR<\/td><td>TI<\/td><td>Nanopower, 0.9V, push-pull<\/td><\/tr><tr><td>LMV7219M7X\/NOPB<\/td><td>TI<\/td><td>7ns high-speed, 1.1mA<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/7451","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/comments?post=7451"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/7451\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media?parent=7451"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/categories?post=7451"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/tags?post=7451"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=7451"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
