The SGM818Y is a low power consumption voltage detector with high accuracy detection. It operates with a supply voltage (VDD) range from 0.9V to 6V. It can provide circuit initialization for DSP-based and processor-based systems. The SGM818Y offers tremendous flexibility with an adjustable threshold that is available from 1.2V to 5V with 0.1V increments.
Whenever VDD falls below a factory preset threshold level (VTH), the device will send out a reset signal. This signal will last the whole period until VDD recovers. Once VDD exceeds the release voltage (VTH + VHYS), the reset signal will maintain a certain delay time and be released.
The SGM818Y is available in Green SOT-23-3 and UTDFN-1×1-4L packages. It is specified over the -40℃ to +125℃ operating temperature range.
