The TAA3033 is an active precharge controller integrated circuit (IC) designed for automotive and industrial applications, including hybrid electric vehicles (HEVs), battery electric vehicles (BEVs) and energy storage systems (ESS). It actively regulates the current to safely pre-charge the DC-link capacitor in xEV traction inverters.

Integrated into the battery management system (BMS), it is typically controlled by the battery junction box (BJB) or battery disconnect unit (BDU).

Operating as a cost-efficient and programmable buck converter, the TAA3033 only requires a few small external components. It eliminates the need for a large power resistor and additional thermal management, simplifying the design and reducing system cost and size.

Features

Controller Specifications

  • AEC-Q100 Grade 1-qualified:: -40 °C to +125 °C ambient temperature range
  • Wide supply voltage ranges from 11 V up to 36 V
  • Supports low-side and high-side operation
  • Suitable to drive silicon (Si) and silicon carbide (SiC) power metal-oxide-semiconductor field-effect transistors (MOSFETs)
  • inter-integrated circuit (I²C) interface for configuration of control parameters
  • Enable input for start-of-pre-charge cycle
  • Ready output for end-of-pre-charge
  • Fault output for triggered protections against switching and connection failures
  • Small outline SO14 package

Controller Functions

  • Regulated precharge current with continuous conduction mode (CCM) control
  • Peak current and ripple adjustable by internal comparator level and external sense resistor
  • Duty-cycle operation with a very wide range from 0.1 % up to 99.9 %
  • Start of pre-charge with a low duty cycle to prevent current run-away
  • End of pre-charge by operation with maximum duty cycle
