The MCP1316T-29LE/OT is a Voltage Supervisor designed to keep a microcontroller in reset until the system voltage has reached and stabilized at a proper level for reliable system operation. These devices also protect from brown-out conditions when the system supply voltage drops below the specified threshold voltage level. As the device VDD rises, the device's Reset circuit will remain active until the voltage rises above the "actual" trip point (VTRIP) plus the hysteresis (VHYS).
