High-Side Current Sensing with Benchmarq's Fast-Charge Control ICs
PDF, 31 Kb, 档案已发布: Sep 5, 1999
A low-side, current-sensing resistor in a fast-charge control circuit generates a small voltage drop between the low side of the battery pack and ground. This drop is not a problem in most cases; however, some applications, particularly mobile communications circuits, are intolerant of any potential difference between the low side of the battery pack and ground. Using a few additional components i
