Microchip Technology, Inc. 3-Pin Reset Monitor TC1272A

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. Additional 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
