Overview

The TPB7462 series is a secondary overcharge hardware protector for 2s, 3s, or 4s lithium-ion battery packs

TPB7462 series provides high accuracy overcharge threshold to avoid the safety risk from battery pack. It also provides the CTL pin to directly control output or connect PTC (Positive Temperature Coefficient) resistor to monitor overtemperature of battery pack.

The TPB7462 integrates a LDO for powering external circuit with extremely low leakage current.

TPB7462 is available in WDFN2x2-8 package. Its operation temperature range is from −40°C to +85°C.
