12V Protection – TPS2592Ax  
5V Protection – TPS2592Bx  
integrated circuit protection and power management  
solutions in a tiny package. With few external  
components and multiple protection modes, they are  
a robust defense against overloads, shorts circuits,  
voltage surges, excessive inrush current, and reverse  
current. Only one external resistor is required for  
setting the current limit level, which has a typical  
accuracy of ±15%. Over voltage events are limited by  
internal clamping circuits to a safe fixed maximum,  
with no external components required. TPS2592Ax  
devices provide over voltage protection (OVP) for  
12V systems and TPS2592Bx devices for 5V  
systems. In cases with particular voltage ramp  
requirements, a dV/dT pin is provided that can be  
programmed with a single capacitor to ensure proper  
output ramp rates. Many systems, such as SSDs,  
must not allow holdup capacitance energy to dump  
back through the FET body diode onto a drooping or  
shorted bus. The BFET pin is for such systems. An  
external NFET can be connected “back to back” with  
the TPS2592xx output and the gate driven by BFET.  
When the TPS2592xx is disabled, then current flow is  
stopped in both directions. TPS2592xL parts will latch  
off after a fault and TPS2592xA parts will attempt to  
restart after the thermal shutoff resets.
