1 General Description The MAX469 evaluation kit (EV kit) is a fully assembled and tested circuit board that demonstrates the MAX469 overvoltage-, undervoltage-, and overcurrentprotection device. The EV kit features an external p-channel MOSFET and LED input and output reading. The EV kit comes with the MAX469ATP+ installed, but can also be used to evaluate the pin-compatible MAX469 and MAX469 devices with IC replacement of U. Request samples from Maxim when ordering the EV kit. Benefits and Features 5.5V to 58V Operating Voltage Range External p-channel MOSFET Proven PCB Layout Fully Assembled and Tested Ordering Information appears at end of data sheet. Quick Start Required Equipment MAX469 EV kit 40V DC power supply 5V DC power supply Multimeter Procedure The EV kit is fully assembled and tested. Follow the steps below to verify board operation: ) Verify that all jumpers are in their default positions. ) Set the 40V DC power supply to 0V and connect to V (TP). ) Connect the 5V DC power supply to VIO (TP). 4) Turn on both power supplies. Verify that LED is on, and FLAG (TP5) is 0V. 5) Increase voltage on the DC power supply to TP and verify that LED turns on when voltage reaches ~.4V. Also check that voltage on V (TP5) is ~.4V and FLAG (TP5) is 5V. 6) Increase voltage on the DC power supply to TP and verify that LED turns off when voltage reaches ~6V. Also check that voltage on V (TP5) goes down and FLAG (TP5) is 0V. 7) Decrease voltage on the DC power supply to TP and verify that LED turns on when voltage reaches ~5V. Also check that voltage on V (TP5) is ~5V and FLAG (TP5) is 5V. 8) Decrease voltage on the DC power supply to TP and verify that LED turns on when voltage reaches ~V. Also check that voltage on V (TP5) goes down and FLAG (TP5) is 0V ; Rev 0; /4

2 Detailed Description of Hardware The MAX469 EV kit is a fully assembled and tested circuit board demonstrating the MAX469 overvoltage-, undervoltage-, and overcurrent-protection device in a 0-pin surface-mount TQFN-EP package. The EV kit also features LEDs to indicate the power for input and output (see Table ). Table. LED Indicator (LED, LED) LED LED LED LED is on when is powered LED is on when is powered Table. Enable Inputs Jumper Settings (JU, JU) Enable Inputs (EN, ) Use jumpers JU and JU to enable the device (see Table for jumper settings). Overvoltage-Lockout Threshold (OVLO) Use jumpers JU and JU5 to select internal or external OVLO threshold. Install a shunt on either JU or JU5, but not both at the same time (see Table 4 for jumper settings). Undervoltage-Lockout Threshold (UVLO) Use jumpers JU4 and JU6 to select internal or external UVLO threshold. Install a shunt on either JU4 or JU6, but not both at the same time (see Table 5 for jumper settings). Table 4. OVLO Threshold Jumper Settings (JU, JU5) JU JU - is connected to V -* is connected to EN is high EN is low Table. Enable Inputs Switch Status EN SWITCH STATUS 0 0 On 0 On 0 Off On JU JU5 * Not installed OVLO is connected to ground; nternal OVLO threshold is used (do not install JU5) OVLO is open OVLO is connected to external voltage-divider; use R/R or R6 to set overvoltage threshold (do not install JU) OVLO is open Table 5. UVLO Threshold Jumper Settings (JU4, JU6) JU4 JU6 * Not installed UVLO is connected to ground; internal UVLO threshold is used (do not install JU6) UVLO is open UVLO is connected to external voltage-divider; use R4/R5 or R7 to set undervoltage threshold (do not install JU4) UVLO is open Maxim Integrated

3 Current-Limit Threshold Use jumpers JU7 JU0 to use different resistors to program the current-limit threshold (see Table 6 for jumper settings). Reverse-Current Blocking Use jumper JU to enable or disable reverse-current blocking (see Table 7 for jumper settings). Table 6.
