Description

Traduction par IA

The SGM804 low-power micro-processor supervisor circuit monitors system voltages from 1.6V to 5V. This device performs a single function: it asserts a reset signal whenever the VCC supply voltage falls below its reset threshold. The reset output remains asserted for the reset timeout period after VCC rises above the reset threshold. The reset timeout is externally set by a capacitor to provide more flexibility. The SGM804 has an active-low, push-pull reset output. It is available in Green SOT-23-5 package and is specified over an ambient temperature range of -40°C to +85°C. The reset output is typically connected to the reset input of a μP. A μPs reset input starts or restarts the μP in a known state. The SGM804 μP supervisory circuit provides the reset logic to prevent code-execution errors during power-up, power-down, and brownout conditions. RESET changes from high to low whenever VCC drops below the threshold voltage. Once VCC exceeds the threshold voltage, RESET remains low for the capacitor-adjustable reset timeout period. This device output is guaranteed valid for VCC > 1V. The SGM804 can be operated in a voltage detector mode by floating the SRT pin. The reset delay times for VCC rising above or falling below the threshold are not significantly different. The reset output is deasserted smoothly without false pulses. The reset timeout period is adjustable to accommodate a variety of μP applications. Adjust the reset timeout period (tRP) by connecting a capacitor (CSRT) between SRT and ground.
