Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TLE7368-2E device is a multi-function power supply circuit designed for automotive power systems using standard 12 V batteries. The device is designed to power and monitor the next generation of 32-bit microcontroller family devices (13 μm lithography) that require 5 V, 3.3 V or 1.2 V voltages. The regulator follows the previous generation TLE6368 design where the pre-regulator output is used as the input to the microcontroller linear power supply.

Feature Description:

Highly efficient next-generation microcontroller power supply system

Wide battery input voltage range < 4.5 V to 45 V

Operating temperature range Tj = -40 °C to +150 °C

Pre-regulator to reduce overall power loss: integrated current-mode buck converter 5.5 V/2.5 A

Post-regulators, e.g. for system and controller I/O supply: LDO1: 5 V ±2%, 800 mA current limit, LDO2: 3.3 V ±2% or 2.6 V ±2% (optional output), 700 mA current limit

Integrated linear regulator control circuitry to power the controller chip: LDO3 control for external NPN power stage: 1.2V ±2%

Backup regulator for off-board power supply: 2 tracking regulators that follow the main 5 V regulator at 105 mA and 50 mA

Backup regulator with very low current consumption: linear voltage regulator for backup power, e.g., for memory circuits, output voltage selectable in hardware between 1.0 V or 2.6 V, current 30 mA, separate battery input isolated from buck regulator inputs

Hardware controlled on/off logic

Undervoltage detection: undervoltage reset circuitry with adjustable power-on reset delay time, backup power supply with undervoltage monitoring circuitry

Window watchdog circuit

Over-current protection for all regulators

Controller power sequencing

Over-temperature shutdown

Packages: Low Rthja Power-P-DSO-36 package, PG-DSO-36 small thermal pad package

PG-DSO-36 only: environmentally friendly product (RoHS compliant)

AEC certified

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
