In the car travel scenario, the emergency start device is a key weapon to deal with the vehicle battery power loss. It can quickly restart the vehicle when the battery is deactivated in the cold winter, the power is zeroed after being left for a long time, and the car lights are forgotten to be turned off. Our company's VB1330 and VBI1695 MOSFET products have outstanding performance in the vehicle emergency start solution.

 1. The key role of MOSFET in vehicle emergency starting

The emergency start of a vehicle is like a "power repair battle" where every second counts. Each link is closely linked, and extremely high requirements are placed on timeliness and accuracy.

1. Electricity “dispatcher” precisely controls the current

When the emergency starter is connected to the vehicle circuit, the power environment in the vehicle is complex and the power requirements of each component are different. VB1330 takes on the responsibility, with 30V VDS and ±20V VGS, accurately adapting to the working conditions and controlling power distribution. The low on-resistance advantage is outstanding, only 33mΩ when VGS is 4.5V, and as low as 30mΩ when 10V, reducing power loss and ensuring efficient operation of the starter motor.

2. Speed: “Pioneer”, quick response to instructions

Emergency start-up cannot be delayed, time is precious. VBI1695 relies on advanced Trench technology to develop fast switching capabilities. With 60V VDS, ±20V VGS and 1.7V threshold voltage, it can instantly capture instructions, switch circuits, and cooperate with VB1330 to deliver power, helping the vehicle to start quickly.

2. The outstanding product advantages of VB1330 and VBI1695

1. VB1330: The Ballast for Stable Power Supply

VB1330 is a single N-type transistor with fine internal polishing, and the electron migration is efficient and smooth. The package adopts SOT23-3, which is compact and has excellent heat dissipation, and is not afraid of long-term high-load operation. Even if the emergency start is frequently operated and a lot of heat is generated, it can be quickly evacuated to maintain stable power output, laying a solid foundation for the emergency start of the vehicle, and it can be called the "ballast stone" of stable power supply.

 2. VBI1695: The “sharp blade” of agile switching

VBI1695 is also a single N-type structure, with excellent performance under the support of Trench process. SOT89 package is conducive to heat dissipation and integration, gate-source resistance is 88 mΩ at VGS = 4.5V, 76 mΩ at 10V, with a rated drain current of 5.5A, it has agile circuit switching capability, easily shields electromagnetic interference in the car, accurately executes instructions, and accelerates the startup process.

3. Prospects for the synergy between vehicle emergency start and MOSFET

Looking to the future, automotive technology is "surging" all the way, and people's expectations for emergency starting equipment are rising. Intelligence and multi-function are the general trend. Emergency starting equipment is expected to be connected to the intelligent network system to "check the pulse" of battery health in real time; link remote rescue, and call for help with one click.

VB1330 and VBI1695 - MOSFET are the backbone of the industry, and technological innovation will not stop. Further reduce the on-resistance, increase the switching speed, enhance stability and compatibility, and adapt to complex electrical systems; integrate fault diagnosis, intelligent current control and other functions. By then, when the car owner encounters a low battery, one-button start, the vehicle will be "revived" instantly, and the car will be worry-free and enjoy the convenience of technology.
