This article presents the reverse polarity protection for DC/DC converters. It describes the series diode protection, as well as the shunt diode, and P-FET polarity protection circuits. This article ...
It’s a problem that’s been around for as long as there have been battery-powered systems: you load the battery the wrong way, with the poles inverted, and create a reverse-polarity event. The system ...
A special control IC that emulates a “smart diode” along with an external MOSFET allows positive inputs and prevents negative inputs for automotive and industrial applications. This new IC replaces ...
When a circuit requires reverse-voltage protection on the power input, the usual approach is a series diode (see the figure, a). But if the input voltage is low—say, two or three AA batteries—the ...
Nexperia has put an ideal diode, including its p-channel mosfet, and reverse polarity protection, in a 2.1 x 1.25 x 0.95mm TSSOP6 package. Called NID5100, it is aimed at industrial and consumer ...
PLANO, Texas, July 23, 2025--(BUSINESS WIRE)--Diodes Incorporated (Nasdaq: DIOD) today introduces the AP74502Q and AP74502HQ automotive-compliant* 80V ideal diode controllers, providing robust and ...
YouTube presented me with a video* about a reverse polarity protection IC, On Semi’s NCV68261, which can also be an ideal diode and a load controller. And, being partial to a nice ideal diode, I ...
The Mychanic Smart Jumper Cables ($25) include the brilliant feature of reverse polarity protection. Live positive to dead positive, live negative to ground—that's the car-jumping wisdom that's ...
