Lm3914 12V Battery Level Indicator at Anthony Blea blog

Lm3914 12V Battery Level Indicator. In this circuit each led indicates 10 percent battery level. We can extend this circuit to 100 steps by cascading lm3914 ic’s. A battery level indicator gives the visual indication of the battery state and so allow disconnecting it before over charging. How to operate battery level indicator circuit? Lm3914 ic senses the voltage levels and drives 10 leds. We can enable bar mode or dot mode by at pin 9 of lm3914 ic. The lm3914 is an analog. 12v battery level indicator with led dot / bargraph display. The heart of this circuit is the lm3914 from national semiconductors. This circuit is simple and easy to build and can be used in cars to monitor the battery status. This 12v battery level indicator circuit contains lm3914 ic which is a dot/bar display driver. This circuit is most suitable for indicating 12v battery level. It uses an ic lm3914 as a voltage level indicator, the ic senses the level of voltages and displays it over leds. Connect battery to be tested to the input of the circuit. Suitable for automobile lead acid batteries.

The working and circuit are explained below. Lm3914 ic senses the voltage levels and drives 10 leds. Connect battery to be tested to the input of the circuit. This circuit is most suitable for indicating 12v battery level. So today, we are going to build a battery level indicator using the lm3914n dot/bar display driver ic. This circuit is simple and easy to build and can be used in cars to monitor the battery status. It uses an ic lm3914 as a voltage level indicator, the ic senses the level of voltages and displays it over leds. The lm3914 can sense voltage levels and can drive a display of 10 leds in dot mode or bar mode. We can extend this circuit to 100 steps by cascading lm3914 ic’s. This 12v battery level indicator circuit contains lm3914 ic which is a dot/bar display driver.
