The LTC4100EG#PBF is a single-chip smart battery charger controller designed to simplify the construction of SBS compliant systems. This IC implements a Level 2 charger function, allowing programming by the battery or host. It monitors battery safety signals, including temperature and connectivity, and maintains SMBus communication even when AC power is removed.
Key electrical specifications include a wide output voltage range of 3.5V to 26V, with a maximum charging current capability of up to 4A. The device boasts high efficiency with a synchronous buck charger design, featuring a low 0.5V dropout voltage and a maximum duty cycle exceeding 98%. Voltage accuracy is ±0.8%, and current accuracy is ±4%. The charger also includes an AC adapter current limit to prevent overloading.
Programming of charge current and voltage is achieved via 10-bit and 11-bit DACs, respectively. User-selectable overvoltage and overcurrent limits enhance system safety and reliability. The LTC4100EG#PBF operates within a temperature range of -40°C to 85°C (TA).
Packaged in a 24-SSOP, this surface-mount component is suitable for portable instruments, data storage systems, and battery backup servers. It supports I²C interface and provides hardware interrupts for status changes.
