1 Introduction
The TPS26600-02EVM allows reference circuit evaluation of TI's TPS2660x devices. The TPS2660x are
compact 4.2-V to 55-V, 2.23-A industrial eFuses with integrated back-to-back FETs, programmable
undervoltage, overvoltage, reverse-polarity, overcurrent, inrush current protection, and output current
monitoring features.
1.1 EVM Features
The TPS26600-02EVM features include:
• 4.2-V to 55-V input operating voltage range
• 0.2-A to 2.23-A jumper-programmable current limit
• Reverse polarity protection up to –55 V
• Programmable input UVLO
• Selectable overload fault response (auto-retry, latch and circuit breaker)
• Programmable input overvoltage protection (OVP) cut off
• Programmable V
OUT
slew rate control
• Load current monitor output with 1.5 V / A
• Optional on-board transient protection devices like input TVS and output Schottky diodes
• On-board reset switch and fault indicators
1.2 EVM Applications
• Control and automation
• PLCs
• Industrial power systems
• Sensors and controls
2 Description
The TPS26600-02EVM enables full evaluation of the TPS2660x devices. The EVM supports HTSOP and
QFN versions of the devices on two channels (CH1 and CH2, respectively). Input power is applied at T1
(CH1) and T3 (CH2) while T2 (CH1) and T4 (CH2) provide an output connection to the load. Refer to the
schematic in
Figure 1 and the test setup in Figure 2 .
S1 and S2 allows U1 and U2 to RESET. A fault (FLTb) indicator is provided by D1 and D7 for CH1 and
CH2, respectively. Scaled current for each can channel be monitored at TP5 and TP14 with a scaling
factor of 1.5 V / A.

Minimum programmable current limit can be changed to 0.1 A by changing the R12 and R24 values to 120 k
Ω
on CH1 and CH2
respectively.
