Controller IC from Diodes Incorporated Simplifies Ideal Diode Emulation to Raise Efficiency of Reverse Discharge Protection Circuitry

Feb 17, 2022

Diodes Incorporated (Diodes) (Nasdaq: DIOD) has announced an ideal diode controller for system protection against reverse discharge. Emulating an ideal diode, by driving a P-channel MOSFET, the DZDH0401DW controller provides the high-side rail isolation necessary for reverse current blocking, in systems up to 40V. The compact size and high performance capabilities of this arrangement mean that it is optimized for use in cordless power tools and autonomous household/garden appliances (such as smart vacuum cleaners and smart lawnmowers). It is also very well-suited to other applications, including OR-ing rectifiers used in the hot-swappable and N+1 redundancy power supplies used in data center servers.
