Car emergency braking flashing device

In traffic accidents, rear-end collisions occur frequently due to sudden braking of the vehicle in front. Rear-end collisions are usually caused by failure to maintain a sufficient safe distance and the brakes cannot stop the vehicle. The time from when you discover an emergency ahead to when you apply the brakes is called reaction time. The length of reaction time directly affects the length of the braking distance. Especially when driving at high speed, a serious traffic accident will occur within one second. The long reaction time does not mean that the driver is slow to react, but that he does not know whether the car in front is applying the brake lightly or hard. When he finds out, two seconds have passed, and it is very likely that he will not be able to brake. If the vehicle in front The brake lights with flashing function are different. When you see the brake lights flashing, you must be stepping on the brakes harder. At this time, you should also step on the brakes harder, and the reaction time will be shortened. Therefore, in addition to letting the car behind you know whether to apply the brake lightly or hard, the flashing brake light is also particularly eye-catching and can remind the car behind you in time.

Output Short-Circuit Protection Reference Design for TPS61088 Boost Converter

This reference design provides an output short-circuit protection solution for the TPS61088 boost converter. This function is implemented through the overcurrent protection (OCP) circuit.

This solution only requires an additional low-cost comparator, a sensing resistor and a small N-MOSFET. By adding this small amount of circuitry, the TPS61088 is protected from output short circuit and overload conditions.
