Infineon BTN7030-1EPA Protected Half-Bridge

Featuring an integrated driver

The Infineon BTN7030-1EPA is a protected half-bridge with an integrated driver, providing protection and diagnosis functions. The device is integrated in SMART7 technology.

Part of the NovalithIC™ family, this half-bridge provides protection and diagnosis functions, making it ideal for many applications in the automotive body domain, such as:

  • Door locks
  • Trunk locks
  • Cinching latch
  • Thanks to the half bridge partitioning, it is also the perfect device whenever an individual half bridge is needed

Interfacing to a microcontroller is made easy by the BTN7030-1EPA integrated driver IC which features logic level inputs, diagnosis with current sense, dead time generation and protection against over temperature, undervoltage, over-current, crosscurrent and short circuit.

The BTN7030-1EPA provides a cost optimized solution targeting low current (<15 A) DC motor applications with 0 – 2 kHz.

  • Easy to use and fast design-in – Driver, MOSFETs, load current sensing and diagnostic and protection functions – all integrated in one package, promoting fast and lean design-in activities.
  • Full flexibility – The BTN7030-1EPA supports brushed DC motors both in halfor H-bridge configuration.
  • Cost and board space optimization – Compared to a discrete solution, our integrated half-bridge solution, the BTN7030-1EPA, saves PCB area and cost on a system level.
  • Improved thermal behavior – This device has an exposed pad which ensures better cooling.
  • Functional safety – The BTN7030-1EPA includes an integrated under voltage, MOSFETs’ over temperature- and overcurrent protection, measured directly in the MOSFETs. In an H-bridge configuration, the BTN7030-1EPA furthermore provides a redundancy case for functional safety.
