The driver for pan and tilt of a security camera was shown in a previous slide. Just as in that example, the design of hot water supply equipment requires low cost, low power consumption, safety, and ease of design. The LV8548MC matches these requirements. Low power usage is obtained by the FET outputs, less than 1 µA in standby, and safety is met by having a 20 V excursion Vmax. This means that even when a surge or external voltage reaches the 12 V power supply of the motor, the IC has sufficient margin to be protected. Another safety feature is the dead time between turning on the high and low FETs to prevent through current. The wave form in the bottom left of the slide shows what happens if one FET turns on before the other finishes turning off. A current pulse occurs as shown on the bottom left waveform, these pulses that are too large will lead to IC breakdown. The SANYO DMOS product waveforms can be seen under the “No flow through current” heading, showing the waveforms with timing to prevent through current.
