The MLX12101 is a protection circuit for automotive sensors. It features small package, low dropout voltage, large temperature range, low supply current, etc.
The MLX12101 sensor protection IC is designed for automotive applications where 5 V ICs are powered through long wiring harnesses. It provides over‑voltage shutdown when the input exceeds 6.8 V and reverse‑polarity protection to prevent negative supply conditions.
The device is supplied in a small SOT‑89 package, operates from a 5 V supply, and features low dropout voltage, low supply current, and a wide temperature range. Electrical specifications, pinout details, and typical circuit diagrams are included in the handbook.
