BQ77216 The BQ77216 family of products provides a range of voltage and temperature monitoring including overvoltage (OVP), undervoltage (UVP), open wire (OW), and overtemperature (OT) protection for li-ion battery pack systems. Each cell is monitored independently for overvoltage, undervoltage, and open-wire conditions. With the addition of an external NTC thermistor, the device can detect overtemperature conditions. In the BQ77216 device, an internal delay timer is initiated upon detection of an overvoltage, undervoltage, open-wire, or overtemperature condition. Upon expiration of the delay timer, the respective output is triggered into its active state (either high or low, depending on the configuration). The overvoltage triggers the COUT pin if a fault is detected, and undervoltage triggers the DOUT pin if a fault is detected. If an overtemperature or open-wire fault is detected, then both the DOUT and COUT will be triggered. For quicker production-line testing, the BQ77216 device provides a Customer Test Mode (CTM) with greatly reduced delay time. LM5163 The LM5163 synchronous buck converter is designed to regulate over a wide input voltage range, minimizing the need for external surge suppression components. A minimum controllable on-time of 50 ns facilitates large step-down conversion ratios, enabling the direct step-down from a 48-V nominal input to low-voltage rails for reduced system complexity and solution cost. The LM5163 operates during input voltage dips as low as 6 V, at nearly 100% duty cycle if needed, making it an excellent choice for wide input supply range industrial and high cell count battery pack applications. With integrated high-side and low-side power MOSFETs, the LM5163 delivers up to 0.5-A of output current. A constant on-time (COT) control architecture provides nearly constant switching frequency with excellent load and line transient response. Additional features of the LM5163 include ultra-low IQ and diode emulation mode operation for high light-load efficiency, innovative peak and valley overcurrent protection, integrated VCC bias supply and bootstrap diode, precision enable and input UVLO, and thermal shutdown protection with automatic recovery. The LM5163 is available in a thermally-enhanced, 8- pin SO PowerPAD™ package. TCAN1044V The TCAN1044V is a high speed controller area network (CAN) transceiver that meets the physical layer requirements of the ISO 11898-2:2016 high-speed CAN specification. The TCAN1044V transceiver supports both classical CAN and CAN FD networks up to 8 megabits per second (Mbps). The TCAN1044V includes internal logic level translation via the VIO terminal to allow for interfacing the transceiver IOs directly to 1.8-V, 2.5-V, 3.3-V, or 5-V logic IOs. The transceiver has a low-power standby mode which supports remote wake-up via the ISO 11898-2:2016 defined wake-up pattern (WUP). The TCAN1044V transceiver also include many protection and diagnostic features including thermal-shutdown (TSD), TXD-dominant time-out (DTO), supply under-voltage detection, and bus fault protection up to ±58 V. TCAN1042HV This CAN transceiver family meets the ISO11898-2 (2016) High Speed CAN (Controller Area Network) physical layer standard. All devices are designed for use in CAN FD networks up to 2 Mbps (megabits per second). Devices with part numbers that include the "G" suffix are designed for data rates up to 5 Mbps, and versions with the "V" have a secondary power supply input for I/O level shifting the input pin thresholds and RXD output level. This family has a low power standby mode with remote wake request feature. Additionally, all devices include many protection features to enhance device and network robustness.
