CJ136

Control and amplifier circuit for wide range oxygen sensors by Bosch, NTK or DENSO

Application & Technical Summary

CJ136

CJ136 is a one-chip solution for controlling oxygen sensors. All circuitry to keep the sensor operational is included in a single chip.

CJ136 supports the continuous regulation of Lambda in the range of ʎ= 0.65 to ∞ (air).

Product benefits

  • Pump current control and measurement
  • Lambda measurement result via SPI interface
  • Nernst cell reference voltage source
  • Extended sensor cell impedance measurement for temperature control
  • OBD II conformity
  • UART interface for cylinder imbalancement measurement

Increased accuracy

For increased accuracy - especially in the lean region - the sensor resistance is measured and regulated accordingly for keeping the sensor temperature at a constant level.
