Infineon Technologies TLE62086GXUMA2

Overview

TLE62086GXUMA2 from Infineon Technologies is a fully protected hex-half-bridge driver IC for automotive DC motor control, integrating six independently configurable high-side and six low-side DMOS power switches. It delivers 0.6 A continuous (1 A peak) per switch, with R_DS(on) = 0.8 Ω @ 25 °C, SPI-based control, overtemperature/overvoltage/undervoltage protection, and 10 μA standby current.

For engineers reviewing the TLE62086GXUMA2 datasheet, TLE62086GXUMA2 pinout, TLE62086GXUMA2 application, or TLE62086GXUMA2 equivalent, key selection criteria include its PG-DSO-28-41 package thermal performance, 16-bit SPI diagnosis interface, quarter-bridge configurability, short-circuit protected outputs, and AEC-Q100 qualification for body electronics and actuator control.

Technical Context

The device implements Infineon's Smart Power Technology (SPT®), monolithically integrating bipolar/CMOS logic with DMOS power stages. All six half-bridges support independent forward, reverse, brake, and high-impedance modes via 16-bit SPI command words with LSB-first transmission synchronized to CLK falling edges.

Internal monitoring includes OV/UV lockout with hysteresis on VS, temperature prewarning and hysteresis-based TSD, and per-channel open-load detection. The VCC-supplied logic domain retains state during VS undervoltage events due to internal POR, while INH-driven standby disables all outputs and reduces current to ~10 μA.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The TLE62086GXUMA2 has a maximum junction temperature of +150 °C, with overtemperature protection activating at +165 °C (typ.) and hysteresis of 15 K. Thermal derating begins above +125 °C ambient in the PG-DSO-28-41 package, requiring ≥20 cm² of 2-oz copper on the PCB thermal pad to sustain 0.6 A per channel continuously.

Can the high-side and low-side outputs be used independently in non-bridge configurations?

Yes - each OUTHx and OUTLx pair is electrically isolated and can be driven separately via SPI commands. This enables use as 12 independent switches, six high-side-only drivers, or mixed topologies like three H-bridges plus two high-side loads, confirmed in Table 3 of the official datasheet.

Does the device support PWM control of motor speed, and what is the recommended frequency range?

Yes - the outputs support PWM commutation up to 20 kHz, with internal timing logic preventing shoot-through during transitions. The datasheet specifies minimum off-time of 1.2 μs and recommends 1–10 kHz for optimal EMI/efficiency trade-off in 12 V automotive DC motor applications.

How does the open-load detection function work, and which outputs support it?

Open-load detection operates on all 12 outputs (OUTH1–6 and OUTL1–6) by measuring output voltage during inactive states. When a high-side output is off and VS is present, >90% VS indicates open load; for low-side outputs, <10% VS during GND-switching confirms continuity. Detection is reported in bits 12–1 of the diagnosis register.
