BL5372 is a low-power real-time clock circuit. It can communicate with the CPU in real time through the I2C two-wire interface circuit. It is mainly used in all systems that need to provide a time base. The chip can generate a variety of periodic interrupt pulses (the longest period can be up to 1 month) and has two time reporting systems. BL5372 has an internal integrated low-power regulated power supply, so it can keep the oscillator working normally at a very low power consumption under harsh environmental conditions (typical value: 400nA@3.6V).

The BL13232E consists of two drivers, two receivers, and a dual charge-pump circuit with ±12kV IEC 61000-4-2 Contact Discharge ESD protection.

The BL2555 Power Distribution Switch features internal current limiting to prevent damage to host devices due to faulty load conditions.

BL1590 is a 3~5.5V wide power supply, half-duplex RS-485 transceiver, which contains one driver and one receiver inside the chip. It can achieve error-free data transmission up to 16Mbps. BL1590 has a built-in failure protection circuit to ensure that the output of the receiver is in a logic high state when the receiver input is open or shorted.

The BL1521 is an 8-Channel Analog Multiplexer and Demultiplexer that is designed for 2.5V to 5.5V VCC operation. It has low on-resistance (40Ω TYP) and very low off-leakage current (1nA TYP). The BL1521 device handles both analog and digital signals.

The TPW4052 is a dual SP4T analog switch suitable for use in analog or digital multiplexer/demultiplexer applications. The switch features three digital select inputs (S0, S1), eight independent inputs/outputs (An, Bn), two common input/output (A, B), and a digital enable input (/E). When /E is HIGH, the switches are turned off.

The TPT3232E is IEC61000 ESD protected, 3.0V to 5.5V powered transceivers that meet the RS-232 standards for balanced communication. Each receiver converts TIA/RS-232 inputs to TTL/CMOS levels.

The TPT1042 is a CAN transceiver that meets the ISO11898 high-speed CAN (Controller Area Network) physical layer standard. The device is designed to be used in CAN FD networks up to 5 Mbps, with enhanced timing margin and higher data rates in long and highly loaded networks. As designed, the device features crosswire, overvoltage, and loss of ground protection from −70 V to +70 V, over-temperature shutdown, with a −30 V to +30 V common-mode input voltage range.

The TPT9H111 is a 3.3V Multipoint-Low-Voltage Differential (M-LVDS) line driver and receiver, which can support 100 Mbps data rates. Driver outputs and receiver inputs are protected against ±8kV ESD strikes without latch-up. The driver output has been designed to support multipoint buses with the loads no less than 30 Ω, and can support the controlled slew rate on drivers.

The TPD160221 is a dual differential channel 2:1 multiplexer/demultiplexer switch for PCIe Gen3.0, Gen4.0, DP1.3, DP1.4, USB3.1, USB3.2, or other high-speed serial interface signals.
