Q: TPS61070 Reverse Polarity Protection by 581446
Hi,
Customer is using the TPS61070 off of 2 AA batteries. They would like to know if the device has reverse polarity protection. Can you assist?
A: Re: TPS61070 Reverse Polarity Protection by 10449The TPS61070 does NOT have built in reverse polarity protection on the input (VBAT). The application note Reverse Current/Battery Protection Circuits http://focus.ti.com/lit/an/slva139/slva139.pdf provides several methods to protect against a reverse battery input condition.
