The device is integrating high-side P-channel and low-side N-channel MOSFETs combined with respective drivers and level shifting stage which allows the conversion of the input logic signals of microcontroller’s embedded core voltage controller to the supply voltage level of the gate drivers.The integrated protection features like output current sensing and limitation and over-temperature protection are allowing system optimization. Central functions like Power-On-Reset is enabling proper start-up behavior.The TLF11251EP is coming in a Grad 0-qualified PG-TSDSO-14 for extended temperature range, the TLF11251LD is using a small, leadless PG-TSON-10 capable for automated optical inspection. Both packages are thermally enhanced using an exposed pad and automotive qualified.EVRC, the Embedded Voltage Regulator for the Core of 2nd generation TriCore™ AURIX™ 32-bit microcontroller is designed to drive a half-bridge consisting of a high-side P-channel and low-side N-channel MOSFET. As the driver is relying on the Vext-domain supplied by the 3.3V- or 5V-LDO of the PMIC, the half-bridge has to be sourced by the same domain. This is increasing the load current on the µC-LDO and the thermal budget of the PMIC. Supplying high-end variants of 2nd generation TriCore™ AURIX™ 32-bit microcontrollers (TC38x/TC39x) with a device like TLF35584/85, the PMIC might come to its limits.The half-bridge should be connected to the output of the pre-regulator, de-loading the µC-LDO significantly to overcome this limitation and increase the system efficiency. To be compliant with the EVRC-concept, level-shifter and drivers have to be added. Those are integrated in TLF11251 together with additional logic and protection to ensure stable operation and enable system optimization.

The device is intended to supply 32 bit micro-controller systems which require different supply voltage rails such as 5V, 3.3V and 2.6V. The regulators for external sensors are also provided. The TLE6368G2 cascades a Buck converter block with a linear regulator and tracker block on a single chip to achieve lowest power dissipation thus being able to power the application even at very high ambient temperatures. The step-down converter delivers a pre-regulated voltage of 5.5V with a minimum current capability of 1.5A. Supplied by this step down converter three low drop linear post-regulators offer 5V, 3.3V, or 2.6V of output voltages depending on the configuration of the device with current capabilities of 800mA, 500mA and 350mA. In addition the inputs of six voltage trackers are connected to the 5.5V bus voltage. Their outputs follow the main 5V linear regulator (Q_LDO1) with high accuracy and are able to drive a current of 17mA each. The trackers can be turned on and off individually by a 16 bit serial peripheral interface (SPI). Through this interface also the status information of each tracker (i.e. short circuit) can be read out. To monitor the output voltage levels of each of the linear regulators three independent undervoltage detection circuits are available which can be used to implement the reset or an early warning function. The supervision of the μC can be managed by the SPItriggered window watchdog. For energy saving reasons while the motor is turned off, the TLE6368G2 offers a standby mode, where the quiescent current does not exceed 30μA. In this stand-by mode just the stand-by regulator remains active. The TLE6368G2 is based on Infineon Power technology SPT which allows bipolar,CMOS and Power DMOS circuitry to be integrated on the same monolithic circuitry.

It delivers a programmable step up voltage (Boost) and a precise 5 V fully short circuit protected output voltage (Buck). The TLE6711G/GL contains a power on reset feature to start up the system, an integrated digital window watchdog to monitor the connected microcontroller and a system enable output to indicate the microcontroller window watchdog faults. The device is based on Infineon’s power technology SPT® which allows bipolar and CMOS control circuitry to be integrated with DMOS power devices on the same monolithic circuitry. The small PG-DSO-20-36 SMD packages of the TLE6711GL meet the application requirements. Furthermore, the build-in features like under- and overvoltage lockout for boost- and buck-voltage and the overtemperature shutdown feature increase the reliability of the TLE6711G/GL supply system.

The device is intended to supply and monitor next generation 32-bit microcontroller families (13 μm lithography) where voltage levels such as 5 V, 3.3 V or 1.2 V are required. The regulator follows the concept of its predecessor TLE6368, where the output of a pre-regulator feeds the inputs of the micro’s linear supplies. In detail, the TLE7368 cascades a Buck converter with linear regulators and voltage followers to achieve lowest power dissipation.
