MPM85000

® MPM85000 Automotive Power Management Device Features  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  Direct support for MOST INIC power status pins  24-pin 4x4 mm2 QFN package with exposed paddle  Temperature range: -40 °C to +110 °C General Description 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. Wakeup event signal detection...
