Low-voltage detect

{{Short description|Electronic circuit to reset on low voltage}}

A low-voltage detect (LVD) is a microcontroller or microprocessor peripheral that generates a reset signal when the Vcc supply voltage falls below Vref. Sometimes is combined with power-on reset (POR) and then it is called POR-LVD.[http://www.eetasia.com/ART_8800555539_1034362_NT_a09d5e77.HTM Microprocessor supervisors]
