Monolithic Linear Battery Charger Operates from Inputs Up to 60V
Monolithic Linear Battery Charger Operates from Inputs Up to 60V
06.04.2017 · Circuits
For charging relatively low capacity batteries, or maintenance charging backup and keep-alive batteries, linear topology battery chargers are valued for their compact footprints, simplicity and affordability. Even so, there is a dearth of linear chargers that accept a 10 V or higher input voltage, leaving many industrial and automotive systems underserved...

This application note presents a circuit that uses a low-power CMOS comparator to provide an LED visual indication of a low-battery condition. This LBO is achieved by pulsing the LED at a low frequency and low duty cycle. The circuit accomplishes this without draining excessive battery current that can lead to permanent battery damage and, ultimately, hazardous waste disposal...

Figure shows two large-signal- measurement methods. The first uses a two-resistor voltage divider and an output buffer, and the second comprises an attenuating inverter and a high-value input resistor. Both of these approaches introduce measurement-linearity errors because only a single resistor dissipates power...
