Description
Experience Level: Entry
I need an electronics designer to produce a single power supply circuit for the purpose of limiting power.
Scope of work
Specify an NPN or PNP MOSFET driven current limiting circuit that limits current output from a DC powersupply (Battery pack). (https://en.wikipedia.org/wiki/Current_limiting)
Input/Output voltage varies from 42 to 60.5 V.
Current limitation: Output current must not exceed 12.3 A at 60.5VDC and 17.6 A at 42 VDC for longer than 2 seconds (to handle transients).
Deliverables
1. Schematic files ready for conversion to PCB design as well as PDF output
2. BOM with part numbers and sources - Active components must have at least two alternatives. Active components should be available in thru-hole as well as surface mount.
3. Analysis of power dissipation of active components and any power resistors for the purpose of mechanical design.
Looking for one week turn-around from initiation to deliverables.
