Introduction
The ZSPM4121 Evaluation Board is a compact system intended to facilitate measuring the performance and
operating characteristics of the ZSPM4121 Under-Voltage Load Switch. The board contains a number of test points to
allow evaluating the functions of the ZSPM4121 (see Figure 2.1 and section 4). It has a solid ground plane.
Note: The default part number for the ZSPM4121 Under-Voltage Load Switch (U1 in the schematic in Figure 6.1) is
ZSPM4121AI1Wxx, where xx refers to the factory-configured voltage threshold which is determined by the version of
the ZSPM4121 Evaluation Board ordered. Contact ZMDI for available board versions.
Note: The default configuration of the Evaluation Board is with the NPG pin pulled up to Vin via R1 and therefore R2
is unpopulated (NL designation in the schematic in Figure 6.1). If the application requires that NPG be pulled up to
Vout, remove R1 and install R2.

Connectors
The board contains the following connectors to external signals and supplies (see Figure 2.1):
4
J1:
Screw terminal connection for Vin supply (Vin+ and GND)
J2:
Screw terminal connection to Vout output (Vout+ and GND)
Probe and Test Points
The board contains the following test/probe points (see Figure 2.1):
TP1/Vin:
Kelvin measurement test point for Vin main input
TP4/Vout: Kelvin measurement test point for Vout output
TP3/NPG: Measurement point for the ZSPM4121’s open-drain N-channel NPG output pin 8 (low indicates
“Power Good”)
TP2/GND: Test point for ground; recommended ground for accurate measurements for Vin
TP5/GND: Test point for ground; recommended ground for accurate measurements for Vout
5
Setup
Connect the input voltage supply for the ZSPM4121 at the J1 screw terminal with the leads connected shown in
Figure 2.1.
The output of the Evaluation Board can be measured at the J2 screw terminal.
Recommendation: Use J1 and J2 only for power connections. Use test points TP1 (Vin) and TP4 (Vout) as Kelvin
connections for accurate voltage measurements (see Figure 2.1).
