PT7M6123NLC4EX Application Fields
The PT7M6123NLC4EX chip is well-suited for automotive applications as it is designed to be very reliable, durable, and user friendly. It is used to control car lighting, charging and battery systems, low-side switches, and power sequencers. It is also used for general purpose input/output (GPIO), motor control, and many industrial applications.
PT7M6123NLC4EX Working Principle
The PT7M6123NLC4EX chip works by connecting an edge-triggered rising-edge-sensitive interrupt to the power control input. When the interrupt is triggered, the power control signal is sent to the output pin, which commands the internal circuit to switch the power FETs to turn off the output. This will stop the flow of current and cause the output voltage to fall. The chip then contains a bandgap-regulated voltage reference and comparator supervisor circuit to monitor the output voltage. When the output voltage is below a certain threshold, the chip will send a signal to the GPIO pin to indicate that the output voltage is low and a reset signal is generated.
The PT7M6123NLC4EX chip also contains a high-side overcurrent and short-circuit protection, which will shut off the output trace if the overcurrent or short-circuit fault occurs. The chip also features a power-on reset and undervoltage lockout protection, which will activate reset/shutdown signal if the supply voltage is too low. The chip also contains a programmable soft-start and tracking/sequencing feature, which allows it to adapt to the various onboard power supply conditions.
