2 Compatibility Across Silicon Versions

Table 2-1 Device Comparison Table
Device Version Part Number Current Limit Range Integrated Clamp for Inductive Loads
A TPS281C30A 1 A–5 A Yes
B TPS281C30B 2 A–10 A Yes
C TPS281C30C 1 A–5 A No
D TPS281C30D 2 A–10 A No

Table 2-1 shows the comparison across different device versions. Version A and B have built-in integrated clamp for inductive load discharge, while version C and D are for non-inductive load driving, or for the need of an external clamp for higher energy dissipation capabilities.

The TPS281C30EVM is compatible across all versions of the TPS281C30. A table of the versions of TPS281C30 and considerations that have to be taken can be found in Table 2-2.

Table 2-2 EVM Considerations Across Silicon Versions
TPS281C30 Version EVM Considerations
A, B

With internal VDS clamp, external clamp is not needed. Make sure D2, R5 are not populated and J9 is disconnected.

The current sense potentiometer, R1, setting can be different between version A and B depending on the loading conditions.

For connections of other jumpers, please refer to Connection Descriptions.
C, D

Without internal VDS clamp, external clamp is needed for inductive load discharge. To clamp the output voltage to 0 V during inductive turn-off, please populate jumper, J9, for a slower discharge. For a faster discharge rate, please disconnect J9 and populate R5, and the output is clamped by the TVS diode, D5.

The current sense potentiometer, R1, setting can be different between version C and D depending on the loading conditions.

For connections of other jumpers, please refer to Connection Descriptions.
