BiCMOS is aimed at mixed-signal ICs, such as ADCs and complete software radio systems on a chip that need amplifiers, analog power management circuits, and logic gates on chip. BiCMOS has some advantages in providing digital interfaces. BiCMOS circuits use the characteristics of each type of transistor most appropriately.
The entire 600 V was dropped across the device, and a large short-circuit current flowed. The devices successfully withstood this severe condition. This was the first demonstration of so-called "short-circuit-withstanding-capability" in IGBTs. Non-latch-up IGBT operation was ensured, for the first time, for the entire device operation range.

In electronics, a latch-up is a type of short circuit which can occur in an integrated circuit (IC). More specifically, it is the inadvertent creation of a low-impedance path between the power supply rails of a MOSFET circuit, triggering a parasitic structure which disrupts proper functioning of the part, possibly even leading to its destruction due to overcurrent.
One style of current limiting circuit is shown in the image. The schematic represents a simple protection mechanism used in regulated DC supplies and class-AB power amplifiers. Q1 is the pass or output transistor. R sens is the load current sensing device. Q2 is the protection transistor which turns on as soon as the voltage across R sens ...
BCDMOS is a complex circuit composed of bipolar, CMOS and DMOS devices. [1] BCDMOS technology allows to drive discrete high voltage components (several hundred of operating voltage) at high frequency while keeping high integration with technology nodes down to 40 nm or 22 nm. Many applications still use process node of 0.35μm in 2023. [2]
A transient-voltage-suppression diode can respond to over-voltages faster than other common over-voltage protection components such as varistors or gas discharge tubes. The actual clamping occurs in roughly one picosecond, but in a practical circuit the inductance of the wires leading to the device imposes a higher limit. This makes transient ...
The bipolar LMV431 by Texas Instruments has a V REF of 1.24 V and is capable of regulating voltages up to 30 V at currents from 80 μA to 30 mA; [55] [56] The low-voltage CMOS NCP100 by ON Semiconductor has a V REF of 0.7 V and is capable of regulating voltages up to 6 V at currents from 100 μA to 20 mA.
The second line of numbers (7645) is a date code; this chip was manufactured in the 45th week of 1976. [2] The 7400 series is a popular logic family of transistor–transistor logic (TTL) integrated circuits (ICs). [3] In 1964, Texas Instruments introduced the SN5400 series of logic chips, in a ceramic semiconductor package.
