The ADI ADBT1001 AFE Digital Controllers feature differential remote voltage sense, current sense, pulse-width modulation (PWM) generation, frequency synchronization, overvoltage protection (OVP), and current sharing. Programmable protection features include overcurrent protection (OCP), OVP limiting, and external overtemperature protection (OTP).
The serial peripheral interface (SPI) programs the parameters, providing extensive programming of the integrated loop filter, PWM signal timing, and soft-start timing. The SPI supports access to many monitoring and system test functions. The built-in checksum and programmable protection circuits improve reliability. A comprehensive graphical user interface (GUI) is included for a simple system and channel configuration and programming of the safety features.
The ADBT1001 4-Ch AFE Digital Controllers are available in a 100-lead LQFP_EP package.
