Abstract :
A SPICE-compatible circuit model for multi-sensor CDPS SENSE-FET (Current Detection and Power Self-Supply Sense Field Effect Transistor) is proposed. Based on the discrepancy in the current flow-lines, the subcircuit model is developed by employing the piecewise model equivalence. A dual-gate controlling model has been included to precisely describe the controllable charging current. Simulations, for main switch current, sense and charging current and transient characteristics, agree well with the Medici results in all the operation regimes.
