BQ77PL900DLR Typical application Circuitry

BQ77PL900DLR

The BQ77PL900DLR is a five to ten-series cell lithium-ion battery pack protector provided by Texas Instruments. This integrated circuit (IC) aims to increase the life of the battery pack while enhancing overall safety.

BQ77PL900DLR Key Characteristics:

1. Cell Protection: The BQ77PL900DLR provides cell protection for lithium-ion and lithium polymer batteries. It monitors individual cell voltages and disables the pack if any of the cells are outside the user-selectable safe operating area.

2. Integrated High-Side FET Drivers: This IC includes high-side FET drivers for charge and discharge FETs that provide protection against inrush currents.

3. Communication: The SMBusTM communication protocol, a two-wire interface that allows straightforward power-related components in a system to interact with the rest of the system, is supported by the BQ77PL900DLR.

4. Configuration: The BQ77PL900DLR is highly configurable, allowing users to program overvoltage (OV), Undervoltage (UV), overcurrent in discharge (OCD), short-circuit in discharge (SCD), and overcurrent in charge (OCC) protection thresholds.

Application Scenarios for the BQ77PL900DLR:

The BQ77PL900DLR finds application in battery protection for devices such as portable equipment, medical instruments, and handheld terminals that employ multi-cell lithium-ion or lithium polymer batteries.

Example Circuit Connection - Battery Protection System:

Here's an example of how the BQ77PL900DLR can be integrated into a battery protection system:

- Pin 1 (VC1 to VC5) and Pins 9 to 13 (VC6 to VC10): These pins are to be connected to the positive terminals of the individual cells in a lithium-ion battery pack for voltage monitoring.

- Pin 2 (VC0): This pin needs to be attached to the battery pack's negative terminal.

- Pins 3 and 4 (DCHG and CHG): These pins are to be connected to the gates of the discharge and charge FETs respectively.

- Pins 17 and 18 (SMBCLK and SMBDAT): These pins are for SMBus communication and should be connected to the corresponding lines of the SMBus controller.

- Pin 20 (VDD): Connect this pin to the supply voltage. The device operates from a supply voltage between 8V and 50V.

Key Design Considerations with the BQ77PL900DLR:

1. Proper Isolation: When implementing the BQ77PL900DLR in a battery management system, ensure there is proper isolation between the high voltage battery side and the low voltage controller side.

2. Correct Sequencing: When connecting the cell terminals, ensure they are connected in the correct sequence for accurate voltage monitoring.

3. Thermal Considerations: Always consider the thermal dissipation aspects as poor thermal design can cause the IC to overheat.

4. Programming: Make sure to program the protection thresholds according to the specification of the battery being used. Incorrect settings can lead to overcharging or over discharging, which can damage the battery or decrease its lifespan.

The BQ77PL900DLR with its protection features and flexibility in configuration provides an efficient solution for safeguarding lithium-ion or lithium polymer batteries in various applications.
