Description
5X00058G01 Emerson redundant system output module
thereby controlling external devices or circuits.
The TPS28225 MOSFET driver is now in mass production and can be ordered through TI and its authorized distributors. This device is available in two packaging versions: a low-cost 8-pin SOICDFN package and a heat dissipation enhanced 3mm x 3mm 8-pin DFN package.
IR2117 is a gate driver integrated circuit designed by IR Corporation in the United States specifically for driving individual MOSFETs or IGBTs. IR2117 is a gate driver designed by IR Corporation in the United States specifically for driving single MOSFETs or IGBTs. It uses high-voltage integrated circuit technology and latch free CMOS technology, and adopts a dual in-line package, which can be used in systems with working bus voltages up to 600V. Its input is compatible with standard CMOS levels, and its output driving characteristics can meet the design requirements of high current driven output stages with the shortest cross conduction time. The application of its floating channel and bootstrap technology allows it to be directly used to drive an N-channel MOSFET or IGBT that operates on the high or low side with a bus voltage of up to 600V.
2. Internal structure and working principle
The internal structure and working principle diagram of IR2117 are shown in Figure 2. It integrates nine unit circuits internally, including a Schmitt trigger, a pulse gain circuit, two undervoltage detection and protection circuits, a level shift network, a NAND gate, a complementary power amplifier output stage composed of two MOSFETs, an RS trigger, and a pulse filter.
During normal operation, if the logic power supply and output power supply of IR2127 are not under voltage, the signal from the user controlled pulse forming unit is first shaped by a Schmitt trigger, then amplified by a pulse gain loop, and level shifted and matched by a level shift network. After being triggered by an RS trigger, it is output by a complementary push-pull output stage to drive an external MOSFET or IGBT. Once either the input logic power supply or the output amplifier stage floating power supply experiences undervoltage, one of the output signals will be blocked, causing the output drive pulse to become low level.
responsible for processing signals from on-site sensors or driving actuator actions. For example, they may need to cooperate with devices such
as BANNER travel switch T30UIPB to receive their transmitted position signals; Or by controlling components such as Burkert solenoid valve 00131421, the on/off of fluid media can be precisely managed.
these modules integrate more complex logic processing capabilities. The core task of a pressure switch is to detect whether the pressure
has reached a preset threshold and output a switch signal. Its function is highly specific and fixed. And modules 5X00058G01 and 1
C31219G01 have the ability to comprehensively judge multiple such switch signals and transmitter signals (such as transmitter 1066-P-HT-60),
and output complex control instructions according to internal logic.
