Can someone please address customer question below?
Customer wants to know specifically how the TPS62113 device will react as a drop-in replacement for the TPS62110. Customer states the following: "We have completed a design using the TPS62110.
Page 14 of its data sheet says “If the low-battery comparator function is not used, connect LBI to ground”, and so we grounded the LBI pin since the comparator is not used in our design. The 62110 parts have a very long lead time, but the 62113 is available now.
Can I load the 62113 instead of the 62110?
Page 15 of the common data sheet describes the enhanced features of the 62113, stating “When the enable (EN) pin is pulled high, only the internal bandgap voltage reference is switched on to provide a reference source for the LBI comparator. As long as the voltage at LBI is less than the LBI trip point, all other internal circuits are shut down, reducing the supply current to 10 μA.
As soon as input voltage at LBI rises above the LBI trip point of 1.256 V, the device is completely enabled and starts switching.” I think this means that if the voltage on the LBI pin #7 is less than 1.256V, the device will not turn on. Since our design connects the LBI pin directly to Ground, I think we may not be able to load the 62113.
