Product Summary
The MCP130T-450I/TT is a voltage supervisory device designed to keep a microcontroller in reset until the system voltage has reached the proper level and stabilized. It also operates as protection from brown-out conditions when the supply voltage drops below a safe operating level. The device is available with a choice of seven different trip voltages and both has open drain outputs. TheMCP130T-450I/TT will assert the RESET signal whenever the voltage on the VDD pin is below the trip-point voltage.
Parametrics
Maximum ratings: (1)VDD: 7.0V; (2)All inputs and outputs w.r.t. VSS: -0.6V to VDD +1.0V; (3)Storage temperature: -65℃ to +150℃; (4)Ambient temp. with power applied: -65℃ to +125℃; (5)ESD protection on all pins: ≥ 2 kV.
Features
