General description

Six Channel Low-Side Switch in Smart Power Technology (SPT) with a Serial Peripheral Interface

(SPI) and six open drain DMOS output stages. The TLE 6232 GP is protected by embedded protec-

tion functions and designed for automotive and industrial applications. The output stages are con-

trolled via an SPI Interface. Additionally all six channels can be controlled direct in parallel for PWM

applications. Therefore the TLE 6232 GP is particularly suitable for engine management and power-

train systems.

Data Sheet TLE 6232 GP Description of the Power Stages 4 low side power switches for nominal currents up to 3A (power stages OUT1 to OUT4). Control is possible by input pins or via SPI. For TJ = 150°C the on-resistance of the power switches is below 500mΩ. 2 low side power switches for nominal currents up to 1.5A (power stages OUT5 and OUT6). Control is possible by input pins or via SPI. For TJ = 150°C the on-resistance of the power switches is below 1Ω.
PAGE 8
Data Sheet TLE 6232 GP The effect of the integrated under-voltage detection is similar to the effect of an external reset at pin Reset (except low current consumption): - locks all power switches regardless of their input signals - clears the fault registers - resets SPI control register Parallel Connection of Power Stages The power stages which are connected in parallel have to be switched on and off simultaneously. In case of overload the ground current and the power dissipation are increasing.

Data Sheet TLE 6232 GP SPI Signal Description CS - Chip Select. The system microcontroller selects the TLE 6232 GP by means of the CS pin. Whenever the pin is in a logic low state, data can be transferred from the µC and vice versa. CS High to Low transition: - diagnostic status information is transferred from the power outputs into the shift register.

Simultaneously the device sends the first SO byte back to the µC.
PAGE 11
Data Sheet TLE 6232 GP - SCON_REG: 8-bit (1 byte) length for serial control of the outputs (serial data bits) - DIAG_REG: 16-bit (2 byte) length. Contains the diagnostic information (2 bits per channel), a common over-temperature bit and a common fault bit. Registers MUX_REG and SCON_REG are writeable as well as readable from the microcontroller. The DIAG_REG can only be read from the µC. This leads to five different control bytes which are recognized by the IC.
PAGE 12
Data Sheet TLE 6232 GP On a reading access the bit pattern of the data byte at the SPI input SI will be ignored. The first SO byte sent out simultaneously by the TLE 6232 GP always contains the common fault bit, the over-temperature bit and the diagnostic information of channels 6 and 5 (2 bits each). Depending on the SI control byte, the second SO byte contains the requested information.

Data Sheet TLE 6232 GP Serial/Parallel Control of the Power Stages 1...6 (SPI-Instructions: WR_MUX, RD_MUX, WR_SCON, RD_SCON) The following table shows the truth table for the control of the power stages 1...6. The register MUX_REG prescribes parallel or serial control of the power stages. The register SCON_REG prescribes the state of the power stage in case of serial control.
