Uninterruptible Power Supply
The MIC5157 and two N-channel MOSFETs provide battery
switching for uninterruptible power as shown in gure (6).
Two MOSFETs are placed source-to-source to prevent cur-
rent ow through their body diodes when switched off. The
Super LDO regulator is continuously enabled to achieve
fast battery switch-in. Careful attention must be paid to the
ac-line monitoring circuitry to ensure that the output voltage
does not fall below design limits while the battery is being
switched in.
