Designed to provide low-battery voltage warning for single-cell Li-ion battery applications, the LTC1998 has the ability to adjust the hysteresis from 10 mV to 750 mV. This is ...

Max756 combine a switch-mode regulator with an N-channel MOSFET, precision voltage reference, and power-fail detector in a single monolithic device. The MOSFET is a “sense-FET” type for best ...

ABLIC claims that its S-19116 Series automotive high-voltage detector has the industry’s fastest detection response time of max. 6.8μs while achieving ultra-low current consumption of 2.0μA typ The ...

A non-contact voltage tester has a battery, and Moinzadeh stresses the importance of doing a live test before you use it to ensure the battery is good. “Start by testing on a known live circuit ...

This is a simple circuit that will indicate a low voltage on a 12V lead acid battery. Many that have golf carts, small EV’s, RV’s, or solar power banks for homes have a number of 12V lead acid ...
