SLUSEJ1 December 2021 TPSM8D6C24
The TPSM8D6C24 devices can operate in programming mode when AVIN and VDD5 are powered above their lower UVLO but VDD5 and PVIN are not powered above their UVLO to enable conversion. In programing mode, the TPSM8D6C24 accepts and respond to PMBus commands but does not enable switching or conversion. While PMBus commands can be accepted and processed with VDD5 lower than 3 V, NVM programming through the Section 7.6.7 command must not be used when VDD5 is less than 3 V.
Programming mode allows the TPSM8D6C24 to complete POR and to be configured through PMBus from a 3.3-V supply without PVIN present.
