MPM85000
Overview
The MPM85000 is an automotive system power management device intended for integration into an Electrical Control Unit (ECU). The MPM85000 includes a very low-power Sleep Mode, supporting wakeup transitions to Active Mode due to multiple signals.
- Low-cost, single-chip solution for Automotive Power Management
- Supports low-power Sleep Mode; wakeup due to: - LIN bus / ECL activity - Local event (e.g. ON switch) - MOST Network optical/electrical activity - Switch-To-Power (STP) event
- Power-supply monitoring: - Configurable voltage trip points - Configurable wakeup from Sleep Mode voltage
- Integrated LIN transceiver - LIN 2.0 compliant - Transmission rates up to 20 kHz - MOST Electrical Control Line (ECL) compliant - Adjustable slew rate for reduced EMI - Over-temperature and low-voltage protection - Short-circuit protection - Optional TXD timeout (MOST ECL compliant)
- Optional I2C Control Port for configuration/status
- Programmable Precision Reset Generator
- 3.3 V MicroPower Regulator for continuous power requirements (e.g. Rx PHY, EOC/FOR, INIC persistent memory)
- Temperature monitoring with programmable alerts
- User available data storage (while in Sleep Mode)
- User available One-Time Programmable (OTP) permanent data storage
