ИС переключателя электропитания – распределение электропитания TPS2066CDGN

Распределитель питания , ограничение по току, высокая сторона, активный высокий, 2 выхода, 5В, 1.61А

The TPS2066CDGN is a dual Power Distribution Switch family intended for applications such as USB where heavy capacitive loads and short-circuits may be encountered. This family offers multiple devices with fixed current-limit thresholds for applications between 0.5 and 2A. The dual family limits the output current to a safe level by operating in a constant-current mode when the output load exceeds the current-limit threshold. This provides a predictable fault current under all conditions. The fast overcurrent response time eases the burden on the main 5V supply to provide regulated power when the output is shorted. The power-switch rise and fall times are controlled to minimize current surges during turn-on and turnoff.

• Accurate ±20% current limit tolerance
• Deglitched fault reporting (FLTx)
• Reverse current blocking
• Built-in soft start
