Hi, I need to protect my PIC16LF84 against reverse polarity. Currently I'm running the circuit of 2 x 1.5 N cells (2/3 AAA). I want to protect the circuitry from the batteries being inserted the wrong way. I'm not keen to put a diode in series with the batteries as I'll loose 0.6V. Thanks, Peter. --- Peter Homann Email: peterh@adacel.com.au Adacel Technologies Ltd _/_/_/ _/_/_/ _/ Phone: +61 3 9596 2991 250 Bay St, Brighton _/ _/ _/ _/ Fax: +61 3 9596 2960 Victoria 3186 _/_/_/ _/ _/ Home: +61 3 9555 5603 AUSTRALIA _/ _/ _/ _/_/_/Mobile: 0414-494578 ------------------------------------------------------------------------
