Subject: [EE] high current reverse battery/overload protection I'm looking for a reversed battery and overload protection device (or circuit) that has something more than a 40A capacity, similar to the=A0 ST Micro RBO40-40G but higher in capacity. I'd prefer a single part like this due to board layout constraints. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
