L5961 - MOST power management device

Description

The L5961 MOST PMD integrates all the discrete circuitry usually necessary to implement power supplies and power management for a MOST node.

It includes intrinsic MOST specific power management together with sophisticated diagnostic and fail-safe functions.

Features

  • 5V or 3.3V / 650mA DC-DC Converter with external sync 5V or 3.3V/ 40mA standby voltage regulator 5V or 3.3V / 60mA switchable voltage regulator Very low quiescent current (zero power mode and ultra zero power mode feature) Power management fully compatible to MOST specification Provides power supply for physical layer and control unit Switch to power pulse generator Reacts on four different wake-up events.
  • Switch to power pulse (STPP).
