4 TPS1HA08x EVM Assembly Drawings and Layout
Figure 2 through Figure 4 show the design of the TPS1HA08x PCB. The EVM was designed using FR4
material on a four-layer (2s2p) board. All components are located in an active area on the top side and
active traces are provided in the top and bottom layers to allow the user to easily view, probe, and
evaluate. Moving components to both sides of the PCB can offer additional size reduction for space-
constrained systems.

5 Current Limit
When IOUT reaches the current limit threshold, ICL, the device can switch off immediately (versions A, B,
and E), or the device can remain enabled and limit IOUT (versions C and D). The TPS1HA08-Q1 will be
available in multiple variants which collectively allow both of these behavior options. In the case that the
device remains enabled (and limits IOUT), the thermal shutdown or energy limit protection feature may be
triggered due to the high amount of power dissipation in the device.
6 Current Sense
High-accuracy current sensing allows real-time monitoring and more diagnostics without further
calibration. A current mirror is used to source a 1/4600 of the load current on SNS pin. The 1-kΩR10
resistor is connected to the SNS pin to convert the current source into a voltage:
VSNS = 1000 × IOUT / 4600
