PT7M1233 Datasheet | Pericom Semiconductor

Features - High accurate: 1.5% (25°C) - Operating voltage range: 1.0V ~ 5.5V - Operating temperature range: -40°C to + 85°C - Detect voltage temperature characteristics: 2.5%  TYP - Output configuration: Bi-dir - Reset timeout period: typical 200ms Pin Configuration PT7M1233/1233A | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| Supervisory Circuit Description The PT7M1233/1233A series are designed to monitor power supplies in µP and digital systems. They provide excellent circuit reliability and low cost by eliminating external ponents and adjustments. The devices perform a single function: assert a reset signal whenever the VCC supply voltage falls below a preset threshold. Reset remains asserted 200ms after VCC has risen above the reset threshold. PT7M1233/1233A are bidirectional output, allowing it to monitor a pushbutton on the reset output. Pin Description Name Type Description I/O Reset Output and Pushbutton Input: RST is asserted when VCC drops below voltage threshold VTH-. Active low. When other devices pull RST low, the reset condition occurs and will remain a reset timeout period at least 200ms.
