Switching solutions with flexible output stages

Product Features

  • Power and control chipset
  • Serial and parallel control for interfacing FETs
  • 2 A Continuous power FET outputs
  • 55 V Internal inductive load clamps
  • Characterized for operation from -40°C to 125°C
The latest Power+ chipsets offer separate FET pre-drivers and power DMOS arrays. This new chipset approach offers you the flexibility to tailor the output stage FETs and on-resistances to meet a specific load requirement. They provide a cost-effective alternative to the traditional single-chip custom solutions, often characterized by high risk and long development time.

This new family offers 6-channel (TPIC46L01/02) and 4-channel (TPIC44L01/02) solutions for switching inductive loads such as solenoids, valves, relays, lamps, and motors.

Typical applications:

  • Engine control systems
  • Automotive Safety systems
  • Industrial control systems
  • Robotics
  • Electronic data processing

Pre-Drivers

The TPIC46L01/02 and TPIC44L01/02 (02 version offers an auto enable) are low-side FET pre-drivers designed primarily for low frequency switching. These devices are cascadable and offer diagnostics with real-time fault status returned through the serial output. The pre-drivers outputs feature inductive voltage transient protection and high impedance inputs with hysteresis.

Power+ Arrays™

The TPIC2601 and TPIC2401 are monolithic power arrays that consist of electrically isolated N-channel, enhancement-mode, DMOS transistors configured with common source and open drains. The devices feature integrated high-current diodes to provide 2000 V ESD protection (human body model) and gate damage overstress protection.

  • System flexibility - the capability to customize the output stage to satisfy drive requirements
  • Cost-effective alternative - improved silicon efficiency and lower total packaging cost
  • Off-the-shelf solution - availability plus low-risk

In separating the power section from the control, this architecture allows a standard pre-driver to interface to various power switches. This offers added benefits over integrated solutions to meet demanding power switching needs.

These devices are available in SSOP and PowerFLEX™ packages.
