It provides precise monitoring of a 3.3V VDD rail and an auxiliary voltage through the SENSE input, with separate open-drain reset outputs for each channel. The device features 0.75% trip-point accuracy, 130 ms power-on reset delay, and manual reset capability. With a typical supply current of only 1.2 \u00b5A, it is ideal for battery-powered and low-power DSP\/microcontroller systems.","working_principle":"The TPS3106K33DBVR operates as a dual-channel voltage monitor with two independent supervision paths. The VDD channel monitors the main supply voltage against a fixed 2.941V threshold (for the K33 variant). When VDD drops below this threshold, RSTVDD is asserted low. The SENSE channel compares an external voltage (divided down) against a 0.551V internal reference, asserting RSTSENSE when the sensed voltage falls below threshold. On power-up, RESET is asserted when VDD exceeds 0.4V and remains low until VDD surpasses the threshold and the 130 ms timeout expires. The MR (Manual Reset) pin can force both outputs low regardless of voltage conditions. The open-drain outputs require external pull-up resistors and allow wired-OR connection with other reset sources.","pin_description":"<table>\n<tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr>\n<tr><td>1<\/td><td>RSTVDD<\/td><td>Output<\/td><td>Active-low reset output for VDD monitor (open-drain)<\/td><\/tr>\n<tr><td>2<\/td><td>GND<\/td><td>Power<\/td><td>Ground<\/td><\/tr>\n<tr><td>3<\/td><td>MR<\/td><td>Input<\/td><td>Manual reset input, active low<\/td><\/tr>\n<tr><td>4<\/td><td>SENSE<\/td><td>Input<\/td><td>Voltage sense input (compares to 0.551V)<\/td><\/tr>\n<tr><td>5<\/td><td>RSTSENSE<\/td><td>Output<\/td><td>Active-low reset output for SENSE monitor (open-drain)<\/td><\/tr>\n<tr><td>6<\/td><td>VDD<\/td><td>Power<\/td><td>Supply voltage and VDD monitor input<\/td><\/tr>\n<\/table>","application_scenarios":"<ul>\n<li>DSP and microcontroller dual-voltage power supply supervision<\/li>\n<li>Portable and battery-powered equipment requiring ultra-low Iq<\/li>\n<li>Wireless communication systems with core and I\/O rail monitoring<\/li>\n<li>Industrial equipment with manual reset requirement<\/li>\n<li>Notebook and desktop computers<\/li>\n<\/ul>","alternative_models":"<table>\n<tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr>\n<tr><td>Texas Instruments<\/td><td>TPS3103K33DBVR<\/td><td>SOT-23-6<\/td><td>Single-channel with PFI\/PFO instead of SENSE<\/td><\/tr>\n<tr><td>Texas Instruments<\/td><td>TPS3106K16DBVR<\/td><td>SOT-23-6<\/td><td>1.6V VDD threshold variant<\/td><\/tr>\n<tr><td>Texas Instruments<\/td><td>TPS3110K33DBVR<\/td><td>SOT-23-6<\/td><td>Push-pull output with watchdog timer<\/td><\/tr>\n<tr><td>Maxim Integrated<\/td><td>MAX809TR<\/td><td>SOT-23-3<\/td><td>Single-channel 3.3V supervisor, simpler<\/td><\/tr>\n<tr><td>Renesas<\/td><td>ISL88001IEHNZ<\/td><td>SOT-23-5<\/td><td>Adjustable threshold supervisor<\/td><\/tr>\n<\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/6707","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/comments?post=6707"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/6707\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=6707"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=6707"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=6707"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=6707"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
