1 / 14 page 2004-2012 Microchip Technology Inc. DS21877B-page 1 TC1272A Features • Precision VDD Monitor • 140 msec Minimum RESET, Output Duration • Output Valid to VDD = 1.2V •VDD Transient Immunity • Small 3-Pin SOT-23B Package • No External Components Applications • Computers • Embedded Systems • Battery-Powered Equipment • Critical µP Power Supply Monitoring Typical Application Circuit General Description The TC1272A 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 driven active within 65 µsec (typ.) 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 TC1272A has a complimentary output. The output of the TC1272A is valid down to VDD = 1.2V. The device is available in a 3-Pin SOT-23B package. The TC1272A device is optimized to reject fast transient glitches on the VDD line. Package Type TC1272A VDD VDD VDD RESET RESET Input Processor 1 2 3 GND GND VDD RESET GND TC1272A 1 2 3 Note: 3-Pin SOT-23B is equivalent to 3-Pin SOT-23B* JEDEC TO-236. 3-Pin Reset Monitor |
