Application Note 145: Programming Options for LTC Power System Management (PSM) Devices
A guide to programming the nonvolatile memory (EEPROM) of LTC Power System Management devices using LTpowerPlay, JTAG, automated production tools, or custom firmware.
Overview
This application note outlines various methods for programming the onboard nonvolatile memory (NVM) of Linear Technology (Analog Devices) Power System Management (PSM) products. It provides detailed procedures for manual programming via the LTpowerPlay GUI, automated command-line interfaces, and the use of JTAG boundary scan for production environments. The document includes recommended circuit designs for I2C/PMBus headers to facilitate debugging and in-system configuration. Hardware references include the LTC2977 power system manager, LTC4415 ideal diode, and Vishay Si1303 PFET for power path management during the programming process.
Use Cases
- Configuring digital power controllers during prototyping
- Production programming of EEPROM-based power management ICs
- Field-reprogramming of power supply parameters
- In-circuit debugging and telemetry monitoring
- Implementing JTAG boundary scan for automated board assembly
