A low voltage detector is provided which detects whether a power supply voltage falls below a predetermined threshold voltage. In the polymer alloy, a dispersed phase having a non-periodic structure with a correlation length of 0. The cross coupled network may be configurable to provide common-mode rejection when operated in a differential or in a single-ended mode of operation. The first acting surface and the second acting surface are located on the first engaging structure. One or more L-shaped brackets are formed from a generally upstanding member and an inwardly extending member.
