Working Principles

The BTS426L1E3062ABUMA1 is a high-side power switch that controls and protects loads in automotive applications. It operates by receiving control signals through the IN pin, which enables or disables the switch. When enabled, the device allows current flow from the battery (VBB) to the load connected to the OUT pin. The SENSE pin provides feedback on the load current, allowing for diagnostic functions.

In case of excessive heat, the overtemperature shutdown feature activates, turning off the switch to prevent damage. Similarly, if a short circuit is detected, the short-circuit protection mechanism kicks in, protecting both the load and the switch. The reverse battery protection ensures that the device remains safe even if the battery is connected with reverse polarity.

Detailed Application Field Plans

The BTS426L1E3062ABUMA1 is widely used in various automotive applications, including: - Electric power steering systems - Transmission control units - Engine management systems - Lighting control modules - HVAC systems - Battery management systems

Its high current capability, low on-resistance, and integrated diagnostic functions make it suitable for controlling and protecting heavy loads in these applications.
