BQ2000SN-B5TRG4 is a battery charger device from Texas Instrument’s PMIC – Battery Chargers portfolio. This product has both switch-mode and linear regulation and power management capabilities.

The device enables rapid battery charging via its switch-mode charging topology and can also support the charging of batteries with very low capacities. The charger has an input current limit of 4A, a maximum trickle current of 150mA, and a minimum trickle current of 100mA. The device also has an adjustable voltage output and an adjustable charge current.

It is soley designed for Li-ion chemistries and is intended to be used in portable and consumer applications. The device is rated at a minimum operating temperature of -20°C and a maximum operating temperature of 85°C.

The BQ2000SN-B5TRG4 specification is 3.3V nominal supply and a low current standby start-up current of 4mA. In addition, it has an internal temperature monitoring feature that allows the device to detect when the battery has become too hot and shut off automatically if necessary.

The device also features a host control interface, which allows the charger to be controlled externally. The charger can be completely automated by utilizing the host MCU and a wide range of digital communication schemes such as UART/I2C/USB, SPI as well as analog signals.

The BQ2000SN-B5TRG4 has two separate power stages which are both integrated. The first is the primary power stage that supports up to 4A of charger current and the second one is the secondary power stage that supports up to 150mA of charger current.

In order to control and regulate the charging process, the BQ2000SN-B5TRG4 relies on several internal components. These components include a MOSFET for charging the battery, a linear regulator for the output voltage, and a control circuit for managing the charging process. The control circuit monitors the battery voltage, current and temperature to ensure safe charging.

The BQ2000SN-B5TRG4 also features over-temperature, over-voltage, over-current and short-circuit protection features which ensure that the device is safe to use. When a fault is detected, the charger will automatically shut-off, protecting the battery and charger.

The BQ2000SN-B5TRG4 is a valuable tool for the battery charging process. It’s the perfect solution for many portable and consumer devices that require high-performance battery charging technology. With the host control interface, the device can easily be merged into any system, allowing for automatic and precise charging of a variety of Li-ion chemistries. With its reliable protection features and adjustable battery charging schemes, the BQ2000SN-B5TRG4 is the ideal battery charger for many of today’s products.
