Withstands 60V transient(load dump).
High amplification efficiency ratings Robust automotive design with integrated protection against overstress conditions, such as short-circuits,electrostatic discharge(ESD), load dump, or over-temperature A very advanced diagnostics processor A proprietary feedback loop architecture, addressing the need for lower system cost and electromagnetic emissions Fully digital processing Ability to drive very low impedance speakers(as low as 1 ohm) Compliance with stop/start and hybrid engine standards.
Protection Reverse voltage protection, load dump protection.
Figure 7 illustrates the behavior of the device during a load dump.
Double-fault conditions such as double battery voltage or load dump do not usually require consideration.
Proposed wind power plant with its own charge controller and load dump.
The MIC5016/7 is protected against automotive load dump, reversed battery, and inductive load spikes of- 20V.
In addition to a broad standard voltage range from 9 to 32 V,it also has integrated load dump protection.
U3(a MAX6397TATA overvoltage protection circuit)provides input protection to the circuit during a load dump, and provides a 3.3VDC power supply for the linear drivers in the MAX16809.
A linear regulator with 13V nominal input voltage can, therefore, dissipate 1.2W,and that level can rise briefly to 4W during a load dump.
The circuit of Figure 6 protects the ECU against reverse-battery conditions and transient negative voltages(D2)and impulse positive overvoltages(load dump and low energy transients) greater than the breakdown voltage of the TVS diode D1.
All members of the LT836x family can operate during cold crank or stop-start events; the maximum input voltage capability of up to 60 V handleshigh input voltage transients such as load dump.
Unfortunately, the typical automotive power-controller IC demands a high-voltage process(40V or higher)to withstand load dumps and other overvoltage transients.
The MAX16800 has a high-input voltage range(up to 40V), so it can connect directly to the car battery without needingfurther protection against voltage surges caused by load dumps on the battery network.
The tests include pulses 1 to 4 of ISO 7637-2, including switching of inductive loads and cranking,but noticeably excludes the load dump pulse(pulse 5, see Table 3 for pulse definitions).
A wide-range adjustable frequency allows the LP886x-Q1 to avoid disturbance for sensitive frequency band. The input voltage range for the LP886x-Q1 is from 4.5 V to40 V to support automotive start-stop and load dump condition.
IOUT≤ 5 mA, When the watchdog timer is activated. Operation temperature range Ta -40°C to +125°C Lead-free(Sn 100%),halogen-free Withstand 45 V load dump AEC-Q100 qualified*2 HSOP-8A package product *1.
A wide-range adjustable frequency allows the LP886xC-Q1 to avoid disturbance for sensitive frequency band. The input voltage range for the LP886xC-Q1 is from 4.5 V to 40 V to support automotive stop,start and load dump condition.
These life-critical applications are also similar in their system requirements: operation over a wide input voltage range;sustaining voltage peaks(load dump) of typically up to 40V from the car battery; and low EMI generation.
The high-efficiency step-down DC-DC converter operates from a voltage up to 28V andis protected from load dump transients up to 42V.
