Integrated over-voltage and under-voltage fault detection per cell means the controller can flag a cell-level violation without polling each tap individually — the interrupt line asserts on a threshold crossing. ## Thermal and package constraints for BOM fit Surface-mount assembly with a moisture sensitivity level typical of exposed-pad LQFP packages — pre-bake before reflow if the floor life has been exceeded.","metaTitle":"MC33771BTA1AE NXP Battery Cell Controller, 7-14 Cells","metaDescription":"NXP MC33771BTA1AE automotive battery cell controller, 7-14 Li-ion cells, SPI interface, -40°C to 105°C, 64-LQFP exposed pad.
