Hi Sir,

May I have you help for TPS24770 function questions as below:

1. What is TPS24770 quiescent current?

2. Why TPS24770 will retry once for latch version? (compare with fast latch version)

Thank you for your kindly help!

Best regards,

Edward,

1. Operating currents are specified in the data sheet EC table for each pin.
2. There are 3 different options (pn's) you can choose. See figure 14 in the DS for differences.

Hi Brian,

Thank you for your help.

For the question 1, what we need is the TPS24770 standby current(quiescent current) during EN is low.

could you kindly share this information for us?

For the question 2, what we need to know is why TPS24771-Latch need to retry once? Why not just shut off and never retry again (like fast latch)?

Thank you.

Best regards,

Edward Chen

Edward,

1) Iq En low has not been characterized. Use the DS EC table limits for En high as a default.

2) Use the TPS24772.
