PG/LDSW Block Function

PG/LDSW Block can switch PG (Power Good) and LDSW (Load Switch) function by EEPROM.

Case of PG Function,

When GPM Block becomes workable, PG pin will change from High to Low to recognize as all boost sequence is completed.

Case of LDSW Function,

This function is used when VGL voltage output is prior to AVDD voltage output.

With below application construction,

”Timing Chart 3” sequence can be realized.

LDSW on delay can be set by the formula below.

LDSW off delay can be set by the formula below.

where:

AVDD is AVDD setting voltage.

Vth is M_LDSW gate threshold voltage

When using the LDSW function, set the delay3 time to be longer than or equal to the sum of the maximum value including the

variation of the load switch ON delay time and VGL soft start time. If the delay3 time setting is short, UVP is applied at startup.
