The BTS712N1XUMA1 is a four-channel smart high-side power switch manufactured by Infineon Technologies. Belonging to the Classic PROFET™ 12V family, this device integrates four vertical N-channel power MOSFETs with advanced protection and diagnostic functions. It is designed for automotive power distribution systems and electronic load control applications requiring reliable switching performance and comprehensive fault protection.
The BTS712N1XUMA1 operates over a supply voltage range of 5V to 34V, making it suitable for both 12V and 24V automotive electrical systems. Its four independently controlled output channels allow multiple electrical loads to be switched and monitored within a single integrated circuit, helping reduce external component requirements and PCB space.
Each channel features a typical on-state resistance of 165mΩ at 25°C and a nominal load current of 1.7A minimum and 1.9A typical when one channel is active, subject to the specified thermal and operating conditions. The device also supports parallel connection of output channels to accommodate higher load current requirements.
The device integrates comprehensive protection functions, including overload protection, current limitation, short-circuit protection, thermal shutdown, and overvoltage protection. Its overvoltage protection also addresses automotive load dump conditions, improving system robustness during electrical transients.
Additional protection features include reverse battery protection, undervoltage and overvoltage shutdown with automatic restart and hysteresis, as well as loss-of-ground and loss-of-supply protection. These integrated functions help protect both the switch and connected loads against abnormal operating conditions.
For improved system monitoring, the BTS712N1XUMA1 incorporates digital open-drain diagnostic outputs and open-load detection in the OFF state. The diagnostic feedback allows a connected microcontroller to monitor load conditions and identify potential faults, supporting more reliable automotive electronic control systems.
The device also features fast demagnetization of inductive loads, CMOS-compatible control inputs, and integrated electrostatic discharge (ESD) protection. Its charge-pump architecture enables high-side switching using an integrated N-channel power MOSFET, providing an efficient alternative to conventional relay-based switching circuits and discrete power components.
The BTS712N1XUMA1 supports resistive, inductive, and capacitive loads, making it suitable for a wide range of automotive body electronics and power distribution applications. Typical controlled loads include automotive lamps, solenoids, actuators, and other 12V or 24V grounded electrical loads, subject to the device’s electrical and thermal specifications.
The device is housed in a 20-pin PG-DSO-20 surface-mount package, providing a compact solution for automotive electronic control units and power management modules. It operates over a junction temperature range of -40°C to +150°C and is designed for automotive-qualified applications.
The Infineon BTS712N1XUMA1 combines four-channel high-side switching, integrated power MOSFET technology, and comprehensive diagnostic and protection functions in one package. It is a suitable solution for automotive power distribution, electronic load management, and intelligent switching systems.
