XB8089D is an IC manufactured by XySemi that is designed for battery protection applications. It is a SOP-8_EP_150mil RoHS device and has a wide operating temperature range from -40C to +125C. It features low on-resistance, fast response time, and low power consumption. The device has an integrated under-voltage lockout (UVLO) and over voltage lockout (OVLO) function that protects the battery from over-charging and over-discharging. It also integrates an over-temperature protection (OTP) circuitry that ensures safe temperature operation of the cell. In addition, it has a cell balancing function, which helps maintain uniform voltage across all cells. This IC is an ideal solution for battery protection applications that require reliable protection and high performance.
