Figure 5. Battery Charger Concept
Uninterruptible Power Supply
The MIC5157 and two N-channel MOSFETs provide battery
switching for uninterruptible power as shown in figure (6).
Two MOSFETs are placed source-to-source to prevent cur-
rent flow 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.
