Introduction
The TPS65381EVM evaluation module (EVM) helps engineers evaluate the operation and performance of
the TPS65381x-Q1 (TPS65381-Q1 or TPS65381A-Q1) multi-rail power supply for microcontrollers in
safety relevant applications. The device is configurable through a serial peripheral interface (SPI) and
specific input pins.
The EVM contains the TPS65381x-Q1 device and some circuitry for basic operation, see Figure 1 for the
top board view of the EVM. It has a connection for an optional TIGER board (not included) to configure the
TPS65381x-Q1 device through the SPI. It can also be used with a microcontroller (MCU) board or other
3rd party SPI tool connected to the TPS65381EVM SPI connections.

TPS65381x-Q1 Description

TPS65381x-Q1 Description
The TPS65381x-Q1 device is a multi-rail power supply designed to supply microcontrollers (MCUs) in
safety relevant applications, such as those found in automotive and industrial markets. The device
supports Texas Instruments’ Hercules™ TMS570 MCU and C2000™ families, and various other MCUs
with dual-core lockstep (LS) or loosely-coupled architectures (LC).
The TPS65381x-Q1 device integrates multiple supply rails to power the MCU, Controller Area Network
(CAN), or FlexRay, and an external sensor. An asynchronous buck switch mode power supply converter
with an internal FET converts the input supply (battery) voltage to a 6-V preregulator output. This 6-V
preregulator supplies the other regulators. The device supports wake-up from IGNITION or wake-up from
the CAN transceiver.
The integrated fixed 5-V linear regulator with internal FET can be used for a CAN or FlexRay transceiver
supply for example. A second linear regulator, also with an internal FET, regulates to a selectable 5-V or
3.3-V output which for example can be use for the MCU I/O voltage.
The TPS65381x-Q1 device includes an adjustable linear regulator controller, requiring an external FET
and resistor divider, that regulates to an adjustable voltage of between 0.8 V and 3.3 V which may be
used for the MCU core supply.
The integrated sensor supply can be run in tracking mode or adjustable output mode and includes shortto-ground and short-to-battery protection. Therefore, this regulator can power a sensor outside the module
or electronic control unit (ECU).
The integrated charge pump to provides overdrive voltage for the internal regulators. The charge pump
may also be used in a reverse-battery protection circuit by using the charge-pump output to control an
external NMOS transistor. This solution allows for a lower minimum-battery-voltage operation compared to
a traditional reverse-battery blocking diode when the device must be operational at the lowest possible
supply voltages.
The device monitors undervoltage and overvoltage on all regulator outputs, battery voltage, and internal
supply rails. A second bandgap reference, independent from the main bandgap reference, is used for the
undervoltage and overvoltage monitoring, to avoid any drifts in the main bandgap reference from being
undetected. In addition, regulator current-limits and temperature protections are implemented.
The TPS65381x-Q1 has monitoring and protection functions, which include the following: watchdog with
trigger and question and answer modes, MCU error-signal monitor, clock monitoring on internal oscillators,
self-check on the clock monitor, cyclic redundancy check (CRC) on non-volatile memory, a diagnostic
output pin allowing the MCU to observe internal analog and digital signals of the device, a reset circuit and
output pin for the MCU, and an enable drive output to disable the safing-path or external-power stages on
detected faults. A built-in self-test (BIST) monitors the device functionality automatically at power-up. A
dedicated DIAGNOSTIC state allows the MCU to check TPS65381x-Q1 monitoring and protection
functions.

While the TPS65381x-Q1 converter offers high efficiency, there may still be high power dissipation. The
power dissipation will vary depending on input supply voltage, output voltages programmed on the various
rails and load currents. The PowerPAD™ package offers an exposed thermal pad to enhance thermal
performance which must be soldered to the copper landing on the PCB for optimal performance. The EVM
PCB provides 2 oz. copper planes on the top and bottom to dissipate heat. Power dissipation and thermal
analysis should be done to ensure the thermal management and design for each specific application and
PCB design.

This section describes the jumpers and connectors on the EVM and how to properly connect, set up and
use the TPS65381EVM.
4.1
I/O Connector Description
Three connectors are placed to supply the device under test (DUT) to get access to different signals for
programming or to measure.
CON1 is the supply connector to provide the battery voltage and offer a connection to SPI.
CON2 is the output connector to deliver the output voltage of the different regulators.
CON3 is a connector to either the SPI of an application circuit, or the optional TIGER board which
provides a universal serial bus (USB) to SPI connection.

Supply
The input voltage range for the converter is VBATP = VBAT_SAFING = 5.8 volts to 36 volts. It should be
supplied to CON1, pin 1 (VBAT_SAFING) and 3 (VBATP) with respect to pin 2 and 4 (GND).
NOTE: VBATP = VBAT_SAFING may be lowered to 4.5 volts after the device has been powered up,
but VDD6 will be in dropout mode (100% duty) cycle, VDD5 will be in dropout and VDD3/5
will be in dropout and may cause RESET state if configured to 5 V mode depending on the
detected output voltage, it will be operational if used in 3.3V mode.

VDD6 Voltage Preregulator
The VDD6 preregulator is supplied by VBATP. Blocking capacitors C8, C9 and C10 are connected from
VBATP to GND, stabilizing the input supply voltage. For long supply cables, additional higher capacitance
capacitors could be helpful. The node SDN6 is the switching node of the buck converter. L1 is the inductor
connected to SDN6 and VDD6. The freewheeling diode D1 allows current flow when the device internal
high-side transistor is turned off. C11 and C12 are the output capacitors of the VDD6 regulator. R16 is the
ESR of C11 and R17 is the ESR of C12 required for stability. C13 is a filter capacitor against high
frequencies.
NOTE: VDD6 output capacitance requires controlled ESR. See the device datasheet electrical
parameters and VDD6 Preregulator section for details on R, L and C choices to ensure
stable and balanced operation of VDD6.
The VDD6 pin is the feedback line to close the control loop of the VDD6 regulator, and is also the supply
node for the VDD3/5 and VDD5 regulators. The output voltage VDD6 is available at CON2, pins 8 and 10.
4.6
VDD1 Voltage Regulator (LDO Controller requiring external FET)
The VDD1 regulator has an internal control amplifier and an external NMOS power transistor. The
regulator is supplied externally by VDD6. C14 stabilizes the input voltage of the VDD1 regulator. The
voltage dividers R13 and R14 define the output voltage and close the control loop to VDD1_SENSE.
Additionally, a minimum required current flows though both resistors. The output capacitors C15 and C16
are needed to stabilize the control loop. The output voltage VDD1 is available at CON1, pin 11, and
CON2, pins 20 and 22.

VDD3/5 Voltage Regulator
The VDD3/5 regulator is supplied internally by VDD6. SEL_VDD3/5 can select the output voltage. If the
pin is open, 3.3 V is selected. If the pin is shorted to GND, 5 V is selected. The output capacitor C6 is
needed to stabilize the output voltage. The output voltage VDD3/5 is available at CON1, pin 9, and CON2,
pins 12 and 14.
4.8
VDD5 Voltage Regulator
The VDD5 regulator is supplied internally by VDD6. The output capacitor C5 is needed to stabilize the
output voltage. The output voltage VDD5 is available at CON1, pin 7, and CON2, pins 16 and 18.
4.9
VSOUT1 Voltage Regulator
VSIN is the supply pin of VSOUT1 voltage regulator. If VSIN is connected to VDD6, lower power
dissipation can be achieved. VSIN is supplied by VDD6 by placing a jumper to short pin 26 and 28 of
CON2. If VSIN is connected to VBATP, output voltages higher than 5V are possible at the expense of
higher power dissipation. To supply VSIN from VBATP, place a jumper to short pin 24 and 26 of CON2.
The capacitor C3 stabilizes the input voltage. The voltage regulator can be used in tracking or nontracking mode. Additionally, the voltage dividers R11 and R12 are used to define the output voltage. The
capacitor C4 is needed for stable operation. The output voltage VSOUT1 is available at CON2, pin 30.
