LM76202-Q1 Evaluation Module
Table 4. Jumper Description (continued)
Jumper Label Description
J4
MODE
Configuration
This jumper configures the device mode for overcurrent and over-load conditions.
OPEN : Circuit breaker mode with auto-retry (MODE = Open)
1-2 : Current limit with auto-retry (MODE = RTN, Default)
2-3 : Current limit with latch-off. (402-k Ω resistor connected MODE and RTN)
J5
ILIM
Configuration
This jumper sets the overcurrent limit.
1-2 : ILIM = 2.23 A
3-4: ILIM = 1.5 A
5-6 :ILIM = 1 A
7-8 : ILIM = 0.2 A
J6
UVLO
Configuration
This jumper configures the input voltage level for UVLO.
OPEN : R2 and R5 resistor are not used for setting UVLO.
CLOSED : R2 and R5 resistor are used for setting UVLO
5 Test Equipment and Setup
5.1 Power Supplies
One adjustable power supply 0-V to 60-V output, 0-A to 10-A output current limit. UCS 200N and LD 200N
for generating transient voltages as per ISO 7637-2 and ISO 16750-2 specifications
5.2 Meters
One DMM needed
5.3 Oscilloscope
A DPO2024 or equivalent, three 10x voltage probes, and a DC current probe
5.4 Loads
One resistive load or equivalent which can tolerate up to 10-A DC load at 60 V and capable of the output
short.
5.5 Test Setup
Before performing any of the test listed in Section 6 , setup the EVM as per steps below:
• Make sure that jumper settings on EVM are set to default position as shown in Table 5
• Connect the power supply, load, oscilloscope and voltmeter to the EVM as shown in Figure 2
• Set the power supply output to zero volts.
• Turn ON the power supply and set the power supply output to 12.5 V and current limit to 10 A.
• Turn OFF the power supply
