Description
AI
The bq76PL536A-Q1 device is a stackable battery monitor and protector for three-to-six lithium-ion cells in series. The bq76PL536A-Q1 integrates an analog front end (AFE) along with a precision analog-to-digital converter (ADC), used to precisely measure battery cell voltages. A separate ADC is used to measure temperature.
In addition to temperature measurement, overvoltage and undervoltage are monitored per channel for protection. Non-volatile memory stores the user-programmable protection thresholds and delay times. A FAULT output signals whenever one of these thresholds is exceeded.
Cell stacks of 192 cells can be supported by stacked bq76PL536A-Q1 devices. A high-speed SPI interface connects all devices.
