Ideal Diode

Ideal Diode

Robust System Protection (Reverse Polarity Protection)
High Integration (Full Safety features & Fast Protection response)
Leading Power Density (Reduces Space requirements and excellent Thermal Performance)

MPS’s automotive ideal diode controllers offer various automotive battery system protection solutions to enable robust protection against reverse polarity and reverse current conditions. These devices provide precise power distribution control throughout the vehicle and replace traditional discrete P-channel MOSFET or Schottky diode solutions while providing additional monitoring, protection, and diagnostics.
