Simple 5V Supply High Side Switcher Wiring diagram Schematic
This is a Simple 5V Supply High-Side Switcher Circuit Diagram. This schema requiring only 10uA of quiescent current, the schema of (Fig. 62-1 (a)) produces only 0.1ohm ON-rises-trance. IC1 is a charge pump voltage converter to produce a 5V level, so analog switch IC2 can provide a 10-V swing to MOSFET Ql.
5V Supply High-Side Switcher Circuit Diagram
This schema uses a voltage converter to enable the analog switch to apply a 4.3V swing to logic level NMOS power transistor Q1. ON resistance is 0.03ohm typical. This schema uses additional stages in the voltage-multiplying schema to provide a higher gate voltage swing. This would enable the use of a converter for an NMOS switching transistor.
