Power chip

It is a three-phase DC brushless driver chip. It can directly drive three NMOS + PMOS half-bridges, and a stable 5V output power supply is integrated inside the circuit.

DC buck regulator, output 5V fixed voltage

The NCV47722 High Side Switch (HSS) is 250 mA per channel and is suitable for harsh automotive environments. The device features high peak input withstand voltage, as well as reverse input voltage, reverse bias, overcurrent, and overtemperature protection. Integrated current sensing (adjustable for each channel with resistors connected to the CSO pin) provides diagnostic and system protection functions. The CSO pin output current produces a voltage drop across the CSO resistor that is proportional to the output current for each channel. Extended diagnostic functions in the shutdown state are also provided, controlled through dedicated input and output pins.

1.6uA static power consumption, 40V withstand voltage, 1A current output, high transient voltage regulation

UC3844B, UC3845B series are high performance fixed frequency current mode controllers. These devices are specifically designed for off-line and DC-DC converter applications, providing designers with a cost-effective solution with minimal external components. These ICs feature an oscillator, temperature compensated reference, high gain error amplifier, current sense comparator, and high current totem pole output suitable for driving power MOSFETs. Also included are protection features with input and reference undervoltage lockouts with hysteresis, cycle-by-cycle current limit, latch for single-pulse metering, and flip-flops for interval shutdown of the output every other oscillator cycle, Output dead time can be programmed from 50% to 70%. These devices are available in 8-pin dual inline plug-in and surface mount (SO-8) plastic encapsulation and 14-pin plastic surface mount (SO-14) encapsulation. The SO-14 encapsulation has separate power and ground pins for the totem pole output stage. The UCX844B has UVLO thresholds of 16 V (on) and 10 V (off), suitable for offline converters. The UCX845B is suitable for low-voltage applications with UVLO thresholds of 8.5 V (on) and 7.6 V (off).
