Infineon Technologies AG Power - Automotive conventional powertrain ICs - Constant Current Control IC for Transmission - TLE8242-2L TLE8242-2L

The TLE8242-2L IC is an eight channel low-side constant current control pre-driver IC Each channel can be configured to function either in direct PWM mode or in constant current mode by setting the appropriate CM bit in SPI message #1. Summary of Features Low side constant current control pre-driver integrated circuit Four independent channels Output current programmable with 11 bit resolution Current range = 0 to 1.2A (typ.) with a 0.2Ohm sense resistor Resolution = 0.78125 mA/bit (typ.) with a 0.2Ohm sense resistor +/- 2% full scale error over temperature when autozero is used Programmable PWM frequency via SPI from approximately 50 Hz to 4 KHz (typ.) Interface and Control 32 Bit SPI (Serial Peripheral Interface) - Slave only ENABLE pin to disable all channels or freeze all channels Active low RESET_B pin resets internal registers to their default state and disables all channels. Open drain FAULT pin can be programmed to transition low when various faults are detected. 5.0V and 3.3V logic compatible I/O Protection Over current shutdown - monitored at POSx pin. Programmable over current threshold Programmable over current delay time Programmable over current retry time Battery pin (BAT) overvoltage shutdown Benefits Sense resistor can be scaled to expand solenoid current range above 1.2A Minimal protection circuitry can be added in order to use the TLE8242-2L in 24V applications (commercial vehicles) Current profile detection feature can be use to determine movement of the solenoid armature Potential Applications Variable Force Solenoids (e.g. automatic transmission solenoids) Other constant current solenoids Idle Air Control Exhaust Gas Recirculation Vapor Management Valve Suspension Control Applications Active suspension control Automotive Automotive body control module (BCM) Body electronics and power distribution EV traction inverter Designers who used this product also designed with TLF35584QKVS1 | OPTIREG™ PMIC TLE9243QK | OPTIREG™ PMIC TLE4253E | OPTIREG™ linear voltage regulators (LDO) BTS7200-4EPA | PROFET™ +2 12V | automotive smart high-side switch TLE4254GA | OPTIREG™ linear voltage regulators (LDO) TLE9255WSK | Automotive CAN transceivers TLS202B1MB V50 | OPTIREG™ linear voltage regulators (LDO) TLF11251EP | OPTIREG™ PMIC TLS105B0MB | OPTIREG™ linear voltage regulators (LDO) SAK-TC387QP-160F300S AE AURIX™ Family – TC38xQP BTS5016-1EKB | PROFET™ + 12V | automotive smart high-side switch TLE7368-2E | OPTIREG™ PMIC SAK-TC375TP-96F300W AA | AURIX™ Family – TC37xTP IPD90P03P4-04 | Automotive MOSFET IPG20N06S2L-65 | Automotive MOSFET BTS7200-2EPA | PROFET™ +2 12V | automotive smart high-side switch BTS7004-1EPP | PROFET™ +2 12V | automotive smart high-side switch BTS7012-1EPA | PROFET™ +2 12V | automotive smart high-side switch TLF35584QVVS1 | OPTIREG™ PMIC BTS7008-1EPP | PROFET™ +2 12V | automotive smart high-side switch TLF35584QKVS1 | OPTIREG™ PMIC TLE9243QK | OPTIREG™ PMIC TLE4253E | OPTIREG™ linear voltage regulators (LDO) BTS7200-4EPA | PROFET™ +2 12V | automotive smart high-side switch TLE4254GA | OPTIREG™ linear voltage regulators (LDO) TLE9255WSK | Automotive CAN transceivers TLS202B1MB V50 | OPTIREG™ linear voltage regulators (LDO) TLF11251EP | OPTIREG™ PMIC 1 2 3 4 5
