This document defines the electrical characteristics and specifications for the Generic DOL Power Module 11867-E01
This document establishes the provisional specification for the Generic DOL Power Module 11867‑E01. It defines the electrical characteristics, interfaces, and thermal properties required for use in electric and hydraulic electric power steering (EPS and HEPS) systems.
Key information includes the module’s three‑phase motor terminals (U, V, W), battery connections (B+ and GND), a fourteen‑pin control interface, and handling requirements for ESD‑sensitive devices. Electrical ratings such as 130 A maximum phase current, 40 V input voltage, and 600 VAC isolation voltage are provided, along with thermal limits up to 175 °C junction temperature.
| Maximum Phase Current (U,V,W) | 130 A |
|---|---|
| Input Voltage (B+ to GND) | 40 V |
| Gate‑to‑Source Voltage | ±20 V |
| Isolation Voltage (Case‑to‑Connector) | 600 VAC |
| Maximum Junction Temperature | 175 °C |
| Operating Case Temperature Range | -40 °C to 100 °C |
It supplies power to the trapezoidal brushless DC motor in electric and hydraulic electric power steering (EPS and HEPS) systems.
The U, V, and W terminals provide the electrical interface with the three phases of the motor.
