MC33771BTP1AE Product Details

NXP's MC33771BTP1AE and MC33772B are reliable, safe, and BOM optimized Li-ion battery management solutions (BMS) with low-cost, robust, high-speed, isolated daisy chain communication. They are designed for automotive and industrial applications such as HEV, EV, ESS, UPS, and others. They support battery packs with 3 to 210 logic cells in series within one daisy chain. The MC33771BTP1AE and MC33772B have lifetime-guaranteed, highly accurate ADC conversions for 3 to 14 differential-cell-voltages measurement channels, one synchronized current sensing, one synchronized coulomb counter, and seven analog input channels. Their embedded balancing transistors supports up to 300 mA passive balancing with dedicated timers and integrated diagnostics. MC33771BTP1AE and MC33772B support ISO 26262 with single chip ASIL-C and up to ASIL-D safety capability. With comprehensive, integrated diagnostics, they enable low BOM and development cost for BMS with high functional safety target..MC33664 is a transceiver physical layer transformer driver designed to conveniently interface a microcontroller to a high-speed, isolated daisy chain communication network. MCU SPI data bits are directly converted to pulse bit information and transferred to the bus network. The sine wave transmission on the daisy chain network guarantees ultra-low radiated emission and robustness. MC33771BTP1AE and MC33772B work as slaves in the daisy chain network. Their response messages use the same structure to send pulse bit information to the MC33664 which is then converted to an SPI bit stream sent back to the MCU. This device is powered by SMARTMOS technology.<strong>Features:</strong> On-chip current sensing, coulomb counter, and power supply, Supporting centralized, distributed daisy chain, distributed CAN, Sleep mode OV/UV and temperature monitor, Scalable SW and HW compatible BMS solution supporting 3 to 210 cells per daisy chain, Integrated passive balancing (300 mA per channel with dedicated timers), Smart grid and home energy storage systems, Robot, Autonomous guided vehicles
