New High-Current PROFET™ - Low-Ohmic Protected High-Side Switch in 5-Pin DPAK

New high-current PROFET™ block diagram

We have further expanded our unrivalled portfolio in the low-ohmic arena with the introduction of BTS 50060-1TEA. This device is a 6mΩ (max 12mΩ @ 150°C) single-channel protected high-side switch, housed in a green and robust 5-pin DPAK package.

Targeted mainly at heating systems (e.g. seat and PTC heaters) and relay replacement, this new PROFET™ can also be used for all types of resistive, capacitive and inductive loads. Optimized edge shaping results in low switching losses and good EMC performance, offering the best balance between power and efficiency. BTS 50060-1TEA can be driven directly from a microcontroller and includes protection functions such as overcurrent and overtemperature shutdown plus diagnostic functions such as open load in ON and OFF state, short-to-battery detection, and accurate load current measurement. In addition, an innovative sense current concept enables simplified end-of-line calibration.

6mΩ RDS(on) (max 12Ω @ 150°C) with inrush current up to 60A EMC optimized performance 3.3 and 5V compitable logic inputs Advanced analog load current sense signal Embedded protection features (e.g. overcurrent shutdown, overtemperature shutdown) Embedded diagnostics features (e.g. open load in ON and OFF state), providing a defined fault signal AEC-qualified green packages (RoHS-compliant) Possibility of high current drive in a small package Low effort for noise filtering Direct connection to MCU Easy current sense calibration Protection of load and device Easy failure detection by distinguishing different failure modes Suitable for lead-free soldering in accordance with IPC/JEDEC J-STD-020
