Voltage Regulators
A voltage regulator is an electronic device that maintains a constant output voltage level, regardless of changes in the input voltage or load conditions. These devices are commonly used to provide a stable power supply to electronic circuits, as well as to protect them from voltage spikes and surges. There are several types of voltage regulators, including linear, switching, and pulse width modulation (PWM) regulators, each with its own set of characteristics and applications. Linear regulators, for example, are simple and efficient, but have a relatively low switching speed and can only provide a limited output current. Switching regulators, on the other hand, have higher switching speeds and can provide a higher output current, but are more complex and require additional components. In addition to their use in power supplies and voltage protection, voltage regulators are also used in a wide range of other applications, including motor control, battery charging, and instrumentation. Flux.ai has the world's largest community-driven public library of voltage regulators, with footprints, symbols, datasheets, and simulation models for a wide range of devices. Whether you're a designer, engineer, or hobbyist, you can find the resources you need to get your project up and running quickly and efficiently.

The L9961 uses a high precision ADC to provide cell voltage, stack voltage and temperature conversion via external NTC. Voltage monitoring functions are cyclically performed with a programmable loop time. Stack current is also monitored via a high accuracy CSA, continuously running and performing also Coulomb counting. Cell balancing is available and can be simultaneously activated on all cells. IC configuration and information exchange for SOC/SOH estimation are performed via I2C peripheral. The IC also integrates a dual pre-driver programmable in both HS/LS configurations for driving pack relays. L9961 also implements battery pack fuse protection to prevent fire and explosion hazards. A 3.3 V regulator with a high current capability is available for supplying pack controller and other external circuitry in both standby and normal operation modes. The IC protects the battery pack against over/under voltage conditions and monitors for over/ under temperature.
