The new HT7Q2552 provides an I²C interface to control system configuration and MCU communication as well as supporting short-current discharge protection, high-voltage wake-up and interrupt return for over-temperature chip protection. This device has been specifically designed for use in a wide range of products such as handheld electronic tools, gardening tools, handheld vacuum cleaners etc.
The HT7Q2552 integrates a battery balance circuitry, a 5V high accuracy regulator, an accurate 2.5V reference voltage output, an individual cell voltage monitor, two discharge N-type MOSFET gate drivers, a charge N-type MOSFET gate driver, a charge/discharge differential current monitor, a discharge short-current protection, two high-voltage wake-up pins and an over-temperature chip protection function. The internal battery balance circuitry provides a balanced cell current without the need for external transistors.
