Texas Instruments TPS2553DRVR

The TPS255x and TPS255x-1 power-distribution switches are intended for applications where precision current limiting is required or heavy capacitive loads and short circuits are encountered and provide up to 1.5 A of continuous load current. These devices offer a programmable current-limit threshold between 75 mA and 1.7 A (typical) through an external resistor. Current-limit accuracy as tight as ±6% can be achieved at the higher current-limit settings. The power-switch rise and fall times are controlled to minimize current surges during turnon and turnoff.

TPS255x devices limit the output current to a safe level by using a constant-current mode when the output load exceeds the current-limit threshold. TPS255x-1 devices provide circuit breaker functionality by latching off the power switch during overcurrent or reverse-voltage situations. An internal reverse-voltage comparator disables the power-switch when the output voltage is driven higher than the input to protect devices on the input side of the switch. The FAULT output asserts low during overcurrent and reverse-voltage conditions.

的tps255x和tps255x-1配电开关是专为应用在精密电流限制是必需的或高电容负载和短路时,提供高达1.5的连续负载电流。这些器件提供了一个可编程的电流限制阈值之间的75毫安和1.7 A(典型)通过外部电阻。电流限制精度为紧6%,可以达到更高的电流限制设置。时间控制以减少通、断时电流电源开关的上升和下降。
tps255x器件电流限制到用恒流模式时,输出负载超过电流限制阈值安全水平输出。tps255x-1器件的闩锁关闭电源开关过电流或反向电压时提供断路器功能。一个内部反向电压比较器禁用电源开关时,输出电压驱动高于输入保护装置的输入端的开关。在过流和反向电压情况下,故障输出断言很低。
