This datasheet introduces the features of TLE6244X, including short circuit protection, overtemperature protection, overvoltage protection, 16-bit serial data input and diagnostic output (2 bits/channel acc. SPI protocol), 16-channel parallel control for PWM applications, low quiescent current, compatible with 3.3V microcontrollers and electrostatic discharge (ESD) protection.
The TLE 6244X is an 18‑channel smart low‑side switch ASSP designed for automotive and industrial power‑train applications. It offers SPI‑based serial control, parallel PWM control for 16 channels, and integrated protection functions such as short‑circuit, over‑temperature, over‑voltage and ESD protection.
The device is supplied in an MQFP64 package, provides on‑chip VDD monitoring, diagnostic error reporting via two‑bit status registers, and optional high‑speed usec‑bus control. Detailed pin assignments, electrical characteristics and fault handling procedures are described in the datasheet.
| Package type | MQFP64 |
|---|---|
| On‑resistance (OUT1‑OUT6) | < 400 mΩ |
| On‑resistance (OUT7‑OUT14) | < 380 mΩ |
| Integrated zener voltage limit (OUT1‑OUT6) | 70 V |
| Integrated zener voltage limit (OUT7‑OUT18) | 45 V |
Each output channel encodes fault conditions in two bits that can be read via the SPI registers.
After each read‑out cycle the registers must be cleared with the DEL_DIA command.
A low signal at pin ABE shuts off the power stages when VDD is outside the permitted range.
Yes, 16 of the 18 channels can be controlled directly in parallel for PWM.
