ИС переключателя электропитания – распределение электропитания TPS2561DRCR

Распределитель питания , ограничение по току, высокая сторона, активный высокий, 2 выхода, 6.5В, 2.5А

The TPS2561DRCR is a dual-channel Power Distribution Switch intended for applications where precision current limiting is required or heavy capacitive loads and short circuits are encountered. This device offers a programmable current-limit threshold between 250mA and 2.8A (typical) per channel through an external resistor. The power-switch rise and fall times are controlled to minimize current surges during turn on and off. Each channel of the TPS256x devices limits the output current to a safe level by switching into a constant-current mode when the output load exceeds the current-limit threshold. The FAULTx logic output for each channel independently asserts low during overcurrent and overtemperature conditions.

• ±7.5% Current-limit accuracy at 2.8A
• 3.5µS (typical) Fast overcurrent response
• Two 44mR high-side MOSFETs
• 2µA Maximum standby supply current
• Built-in soft-start
