TCM809SENB713 Datasheet

PMIC - Supervisors >


The TCM809SENB713 and TCM810 are cost-effective system supervisor circuits designed to monitor VDD in digital systems and provide a reset signal to the host processor,when necessary. No external components are required.The RESET output is typically driven active within 65 μsec of VDD falling through the reset voltage threshold.RESET is maintained active for a minimum of 140 msec after VDD rises above the reset threshold.The TCM810 has an active-high RESET output, while the TCM809SENB713 has an active-low RESET output. The output of the TCM809/TCM810 is valid down to VDD = 1V.Both devices are available in 3-Pin SC-70 and SOT-23B packages.The TCM809SENB713 /TCM810 is optimized to reject fast transient glitches on the VDD line. A low supply current of 9 μA (typ., VDD = 3.3V) make these devices suitable for battery-powered applications. TCM809SENB713 Features • Precision VDD Monitor for 2.5V, 3.0V, 3.3V, 5.0V Nominal System Voltage Supplies• 140 msec Minimum RESET Time Out Period• RESET Output to VDD = 1.0V (TCM809)• Low Supply Current, 9 μA (typ.)• VDD Transient Immunity• Small 3-Pin SC-70 and SOT-23B Packages• No External Components• Push-Pull RESET Output• Temperature Range: - Industrial, SC-70 (E): -40°C to +85°C - Extended, SOT-23, SC-70 (V): -40°C to +125°C TCM809SENB713 Applications • Computers• Embedded Systems• Battery-Powered Equipment• Critical Microcontroller Power Supply Monitoring• Automotive
