Speed PROFET™ Motor Drive High-Side Switch

New High Current PROFET™ block diagram

The Speed PROFET™ BTF 50060-1TEA is a 6mΩ (max. 12mΩ @ 150°C) single-channel protected high-side switch, able to switch at frequencies of 25kHz and above. Housed in a DPAK 5-pin package, it offers a cost-competitive solution capable of driving, controlling and protecting a 12V DC motor (e.g. 100W) or valve.

In combination with a freewheeling diode or a low-side switch, the Speed PROFET™ can be set up in a half-bridge or buck converter topology. It can be driven with a 33kHz PWM signal directly from a microcontroller without necessitating an external bootstrap capacitor, thus enabling an easy and space-optimized board layout.

The device includes protection functions such as short-circuit and overtemperature shutdown plus diagnostic functions like open load in ON and OFF state, and accurate load current measurement.

PWM capability of 33kHz and beyond 6mΩ RDS(on) (max 12mΩ @ 150°C) with inrush current up to 60A No external bootstrap capacitor necessary 3.3 and 5V-compatible 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 Short-to-battery detection AEC-qualified green & robust packages (ToHS-compliant according to J-STD-020B)

Most suitable for driving loads with PWM frequencies from 0Hz (DC operation) up to 33kHz and above Drives valves, coils and motors with inrush currents up to 60A All types of resistive, inductive and capacitive loads
