TPS2051BDBVR, Переключатель силовой нагрузки

Описание TPS2051BDBVR The TPS2051BDBVR is a Single Current Limited Power Distribution Switch intended for applications where heavy capacitive loads and short-circuits are likely to be encountered. This device incorporates 70mR N-channel MOSFET power switches for power-distribution systems that require multiple power switches. Each switch is controlled by a logic enable input. Gate drive is provided by an internal charge pump designed to control the power-switch rise times and fall times to minimize current surges during switching. The charge pump requires no external components. When the output load exceeds the current-limit threshold or a short is present, the device limits the output current to a safe level by switching into a constant-current mode, pulling the over-current logic output low. When continuous heavy overloads and short-circuits increase the power dissipation in the switch, causing the junction temperature to rise, a thermal protection circuit shuts off the switch to prevent damage. • 70mR High-side MOSFET • 500mA Continuous current • Thermal and short-circuit protection • Accurate current limit (0.75A minimum, 1.25A maximum) • 2.7 to 5.5V Operating range • 0.6ms Typical rise time • Under-voltage lockout • Deglitched fault report (OC) • No OC glitch during power up • 1µA Maximum standby supply current • Green product and no Sb/Br ТипОбщего НазначенияКонфигурацияHigh SideКоличество выходов1Соотношение - вход: выход1:1Тип выходаn-каналНапряжение нагрузки, В2.7…5.5Выходной ток (Max), А0.5Сопротивление канала Rds(on) (Typ), Ом0.095Интерфейсon/offРабочая температура, °C-40…+125Корпусsot-23-5Вес, г0.08
