The SGM42203Q is an automotive-grade, Q1-level, high-side driver with a voltage operating range from 4.5V to 36V, and an absolute maximum rating of 60V (ABS). It features a dual-channel high-side driver with a 80mΩ current setting. The overcurrent threshold can be programmed via the CL pin, allowing for settings of 2.5A, 5A, 10A, 15A,
and 22A. The device supports up to 260mJ of inductive load clamping energy.
In case of low-energy spikes on VCC, the internal VCC voltage clamp protects the device.
Table 1: SGM42203Q provides the following protection features.

Figure 1: SGM42203Q Application Circuit Diagram.
To achieve the above-mentioned switching drive, functional protection, and fault diagnostics, we also conducted the following board-level application tests for our customers:
- Automotive EMI/EMC ISO7637-2 testing.
- Evaluation testing of BCI large-current injection interference.
- AEC-Q100-012 repetitive short-circuit cycles and SOA lifetime testing.
