产品概述

TMI6283H is composed of one channel power  switch (Switch1) and one channel load switch  (Switch2) in a 16-pin 3mm x 3mm QFN Package. The  device can be used in series with the front and back  stages, or the two chips can be used separately. The Switch1 is a single channel line power switch  with low on-resistance 60mΩ typical. Input voltage  range could support from 2.7V to 18V with 5.8V  output voltage clamp and 18.9V input overvoltage  protection. The switch1 is controlled by an active  high enable pin. A programmable soft-start  function could be used to set the proper rising time  to reduce inrush current caused by large load  capacitance. Current protection and thermal  shutdown function protect the device against over  current and high junction temperature. The Switch2 is a cost-effective, low voltage, single  P-MOSFET load switch. The switch operates with  inputs ranging from 2.5V to 6V, The switch's low  Rds(on) 60mΩ with meets USB voltage drop  requirements. A built-in P-channel MOSFET with  true shutdown function to eliminate any reversed  current flow across the switch when it is powered  off. When the output voltage is higher than input  voltage, the power switch is turned off by internal  output reverse-voltage comparator. The Switch2  offers a programmable curre nt limit threshold via  an external resistor on ILIMIT2 pin to GND. FLAG2  is an open-drain output report over-current or over  temperature event. In addition, FLAG2 also has  typical 2.5ms deglitch timeout period and reports  output reverse-voltage condition.
