The TPS2660x devices are compact, feature rich high voltage eFuses with a full suite of protection features. The wide supply input range of 4.2 to 60 V allows control of many popular DC bus voltages. The device can withstand and protect the loads from positive and negative supply voltages up to ±60 V. Integrated back to back FETs provide reverse current blocking feature making the device suitable for systems with output voltage holdup requirements during power fail and brownout conditions. Load, source and device protection are provided with many adjustable features including overcurrent, output slew rate and overvoltage, undervoltage thresholds. The internal robust protection control blocks along with the high voltage rating of the TPS2660x helps to simplify the system designs for Surge protection.
A shutdown pin provides external control for enabling and disabling the internal FETs as well as placing the device in a low current shutdown mode. For system status monitoring and downstream load control, the device provides fault and precise current monitor output. The MODE pin allows flexibility to configure the device between the three current-limiting fault responses (circuit breaker, latch off, and Auto-retry modes).
The devices are available in a 5-mm × 4.4-mm 16-pin HTSSOP as well as 5-mm x 4-mm 24-pin VQFN package and are specified over a –40°C to +125°C temperature range.

dVdT | 12 | 20 | I/O | A capacitor from this pin to RTN sets output voltage slew rate See the Hot Plug-In and In-Rush Current Control section |
FLT | 14 | 22 | O | Fault event indicator. It is an open drain output. If unused, leave floating |
GND | 9 | 17 | — | Connect GND to system ground |
ILIM | 11 | 19 | I/O | A resistor from this pin to RTN sets the overload and short-circuit current limit. See the Overload and Short Circuit Protection section |
IMON | 10 | 18 | O | Analog current monitor output. This pin sources a scaled down ratio of current through the internal FET. A resistor from this pin to RTN converts current to proportional voltage. If unused, leave it floating |

OVP | 5 | 12 | I | Input for setting the programmable overvoltage protection threshold (For TPS26600/1 only). An overvoltage event turns off the internal FET and asserts FLT to indicate the overvoltage fault. Connect OVP pin to RTN pin externally to select the internal default threshold. For overvoltage clamp response (TPS26602 Only) connect OVP to RTN externally |
PowerPadTM | — | — | — | PowerPad must be connected to RTN plane on PCB using multiple vias for enhanced thermal performance. Do not use PowerPad as the only electrical connection to RTN |
RTN | 8 | 15 | — | Reference for device internal control circuits |
SHDN | 7 | 14 | I | Shutdown pin. Pulling SHDN low makes the device to enter into low power shutdown mode. Cycling SHDN pin voltage resets the device that has latched off due to a fault condition |
UVLO | 3 | 10 | I | Input for setting the programmable undervoltage lockout threshold. An undervoltage event turns off the internal FET and asserts FLT to indicate the power-failure. Connect UVLO pin to RTN pin to select the internal default threshold |
