The document introduces the features and characteristics of the TLE 6263 automotive and industrial system basis chip from Dinghao. The chip integrates LS CAN, LDO, and HS switch functions, and features a standard fault tolerant differential CAN transceiver, bus failure management, low power mode management, receive only mode for CAN, CAN data transmission rate up to 125 kBaud, low-dropout voltage 5V regulator, high side switch, 2 wake-up inputs, power on and under-voltage reset generator, window watchdog, fail-safe output, early warning feature, sense comparator input, standard 8 bit SPI interface, flash program mode, wide input voltage range, and wide temperature range.
The TLE6263 is a monolithic integrated circuit in an enhanced‑power P‑DSO‑28‑18 package, optimized for automotive electronic control units. It combines a low‑speed differential CAN transceiver, a low‑dropout 5 V regulator, and an SPI interface for monitoring and control.
Key features include a high‑side switch, two wake‑up inputs, a window watchdog with fail‑safe output, early‑warning and sense‑comparator inputs, and a standard 8‑bit SPI interface. The device operates over a wide voltage and temperature range and supports multiple operation modes such as normal, receive‑only, standby and sleep.
