Lm74700qdbvtq1 monitoring and reset chip Ti original spot
explain
Lm74700-q1 is an ideal diode controller conforming to the automotive AEC Q100 standard. It works with an external n-channel MOSFET and can
As an ideal diode rectifier, low loss reverse protection is realized by using 20mV forward voltage drop. The wide power input range of 3.2V to 65V can realize
Control of many common DC bus voltages (e.g. 12V, 24V and 48V automotive battery systems). 3.2V input voltage support (applicable to automobiles)
Severe cold start requirements in the system. The device can withstand negative power supply voltage as low as – 65V and provide load protection.
The device adjusts the forward voltage drop to 20 mV by controlling the gate of the MOSFET. This current regulation scheme can support stability in reverse current events
Shut down and ensure zero DC reverse current. The device can quickly (< 0.75 µ s) respond to reverse current blocking, so it is applicable to ISO7637
Pulse test and systems requiring output voltage to be maintained under power failure and input micro short circuit conditions.
The lm74700-q1 controller can provide a charge pump gate driver suitable for external n-channel MOSFETs. The high voltage rating of lm74700-q1 helps simplify the system design for automotive ISO7637 protection. When the enable pin is at the low level, the controller turns off and consumes about 1 µ a of current.
