HT7Q2552 Overview
Description
The HT7Q2552 is a high voltage analog-front-end IC for 3 to 8 cell Li-ion rechargeable battery protection. It consists of a 5V high accuracy regulator, an accuracy 2.5V reference voltage output, an individual cell voltage monitor, two discharge paths, i.e., low-side power switch gate drivers, a charge path, i.e., high-side power switch gate driver, a charge/discharge differential current monitor, and a discharge short-current protection.
Key Features
- VIN input ranges from 7.5V to 36V
- Individual cell voltage monitor outputs 1/2 of battery cell voltage, when the analog output is 2.1V, it has an accuracy of ±7.5mV
- Internal cell balance switches
- Integrated voltage regulator with 5V/50mA and ±1% accuracy
- At Ta=-40oC~85oC, 2.5V reference voltage output with a maximum variation of 15mV in temperature drift
