Hi Kygo

BU4216 is supervisor IC with programable RESET delay time. TLV840 , TLV841M are best fir for it.

TLV840/841M has better threshold accuracy and lower supply current compare to BU4216. TLV841M has ultra small YBH package (0.73mm*0.73mm) which is very useful in area constrained applications.

Hi Trailokya

It seem that we currently do not have the 1.6V option for the TLV840-Q1, this is only available with the TPS3840-Q1.

This Rohm device has a 1.6V threshold voltage so TPS3840DL16DBVRQ1 was proposed as closest alternative ,right ?

The BU4216F is not p2p with TPS3840 as it has 4 pins compared to the 5 on TPS3840.
