Resets and supervisors Portfolio overview Run your application with carefree supervision Reset is a mandatory function to ensure proper wake-up of complex systems but also reboot in case of failing or frozen applications. With the democratization of microprocessing units, there is an ever-increasing need for resets and supervisors. ST’s portfolio includes: - basic or multi-voltage resets - single or dual pushbutton Smart Resets™ - more advanced supervisors with watchdog, early power-fail detection, battery switchover functions APPLICATIONS • Portable consumer devices KEY BENEFITS • Computers • Software freeze recovery • Video games • Power failure protection • Toys, electronic games • Increased end-product robustness • Set-top boxes, Blu-ray players • Increased end-user perception of • Fitness/wellness equipment quality • White goods • Home automation • Metering • Industrial equipment • Point of sales • Medical equipment • Healthcare devices Scan this QR-code to access documentation and application notes www.st.com/reset VOLTAGE DETECTORS Package Output Reset threshold (V) Reset timeout delay (s) Supply current (µA) Operating temperature (°C) STM1061 SOT23-3 Open drain, active low 1.6 to 5.5 n/a 0.9 -40 to 85 STM1831 SOT23-5 Open drain, active low 1.6 to 5.7 adjustable 0.8 -40 to 85 Package Manual pushbuttons Reset pulse width (ms) Reset setup delay (s) Other Operating temperature (°C) STM6519 DFN6 1 1.28 to 360 0.5 to 10 Test mode -40 to 85 STM6524 DFN6 2 1.28 to 360 0.5 to 10 Test mode -40 to 85 Package Timeout period Output type Chip enable Supply current (µA) Operating temperature (°C) SOT23-5 SC70-5 3.4 ms 6.3 ms 102 ms 1.6 s Open drain or push pull Yes 13 -40 to 85 Part number SMART RESETS Part number WATCHDOGS Part number STWD100 Note : Automotive grade availability on request SUPERVISORS Part number Package Output Watchdog input STM6321 SOT23-5 Push pull, active high Open drain, active low X STM6822 SOT23-5 Open drain, active low X STM706 SO8 Push pull, active low X STM795 SO8 Open drain, active low STM819 SO8 Push pull, active low Watchdog output Manual reset input Power fail in/ out Battery switch over Chip enable gating X X Battery freshness seal Vcc switch output X X X X X X Delayed manual reset input Reset 1 threshold (V) X X X RESETS Part number Package Monitored voltages Output Reset pulse width (ms) Manual reset input STM6315 SOT143 1 Open drain, active low 1.5 to 1680 Yes STM809 SOT23-3 1 Push pull, active low 210 STM6779 SOT23-6 2 Open drain, active low 210 STM6710 SOT23-6 4 Open drain, active low 200 STM6904 TSSOP8 4 Open drain, active low STM6905 TSSOP8 5 Open drain, active low Reset 2 threshold (V) Reset 3 threshold (V) Reset 4 threshold (V) Reset 5 threshold (V) 2.63 to 4.63 2.63 to 4.63 1.58 to 4.63 Adjustable Optional 5, adjustable 3.3 1.8 to 2.5 1.8, adjustable 210, 420 Yes 2.87 to 3.08 1.05 to 2.33 Adjustable Adjustable 210 Yes 2.87 to 3.08 1.05 to 2.33 Adjustable Adjustable Yes Adjustable © STMicroelectronics - November 2013 - Printed in United Kingdom - All rights reserved The STMicroelectronics corporate logo is a registered trademark of the STMicroelectronics group of companies All other names are the property of their respective owners Order code: FLCAREFREE1113 For more information on ST products and solutions, visit www.st.com
