Seller information liaoxiyuan Many of the modern battery technologies have a fairly flat discharge characteristic and the amount of extra time of battery life one gets with a lower drop solution is not that great.

It is possible to construct a battery holder that will not connect if the cells are inserted the wrong way. There is no doubt that the P-FET solution costs a little bit more in part price.

This prevents the flat negative terminal from ever touching it if the battery is inserted in reverse. Michael’s second solution is very elegant I haven’t come across that before but for your situation I’d say it’s overkill. Refer to eBay Return policy for more details.

The MCP is not going to provide reverse polarity protection for your device. You would have to ask yourself how likely it would be that a reverse polarity condition could happen and then decide from that whether you need protection for that scenario.
Delivery times may vary, especially during peak periods. Image not available Photos not available for this variation. The item you’ve selected was not added to your cart. Please enter a valid ZIP Code.
Diode in parallel with power supply. This exposes the circuits to the reverse diode level voltage for whatever 10s or s of milliseconds it takes for the poly fuse to act.

For over-voltage protection replace the diode with a zener. You can select a Schottky diode sii2323 minimize the forward voltage drop so that you can get more usable voltage range from your battery supply. The usual way is to have a couple of plastic lugs each side of the positive terminal.
