Hot-selling and scarce TPS2052BDR Current-Limited Power-Distribution Switches SOP8 spot stock

Product Descriptions

The    TPS20xxB    power-distribution    switches    are intended  for  applications  where   heavy  capacitive loads and short circuits are likely to be encountered. These    devices    incorporates    70mΩ    N-channel MOSFET    power   switches   for    power-distribution systems  that   require   multiple   power  switches   in a  single  package.  Each  switch  is  controlled  by  a logic  enable  input.  Gate  drive  is  provided  by  an internal charge pump designed to control the powerswitch  rise times and fall times to  minimize current surges during switching. The charge  pump  requires no  external  components  and  allows  operation  from supplies as low as 2.7V.

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 overcurrent ( OCx) 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. Recovery from a thermal shutdown is automatic once the device has cooled sufficiently. Internal  circuitry  ensures  that  the  switch  remains off  until  valid  input  voltage  is  present.  This  powerdistribution switch is designed to set current limit at1A (typical).
