description  
The TPS201x family of power-distribution switches is intended for applications where heavy capacitive loads  
and short circuits are likely to be encountered. The high-side switch is a 95-mΩ N-channel MOSFET. Gate drive  
is provided by an internal driver and charge pump designed to control the power switch rise times and fall times  
to minimize current surges during switching. The charge pump operates at 100 kHz, requires no external  
components, and allows operation from supplies as low as 2.7 V. When the output load exceeds the current-limit  
threshold or a short circuit is present, the TPS201x limits the output current to a safe level by switching into a  
constant-current mode. Continuous heavy overloads and short circuits increase power dissipation in the switch  
and cause the junction temperature to rise. If the junction temperature reaches approximately 180°C, a thermal  
protection circuit shuts the switch off to prevent damage. Recovery from thermal shutdown is automatic once  
the device has cooled sufficiently.  
The members of the TPS201x family differ only in short-circuit current threshold. The TPS2010 is designed to  
limit at 0.4-A load; the other members of the family limit at 1.2 A, 2 A, and 2.6 A (see the available options table).  
The TPS201x family is available in 8-pin small-outline integrated circuit (SOIC) and 14-pin thin shink  
small-outline (TSSOP) packages and operates over a junction temperature range of –40°C to 125°C. Versions  
in the 8-pin SOIC package are drop-in replacements for Siliconix’s Littlefoot power PMOS switches, except  
that GND must be connected.
