FS5600

Automotive buck regulator and controller with voltage monitors and watchdog timer

15.6 I2C communication

Communication with the FS5600 is done through I2C, and it supports high-speed

operation mode with up to 3.4 MHz operation. SDA and SCL are pulled up to VDDIO

typically with 2.2 kΩ resistors for 400 kHz operation, and 500 Ω for 3.4 MHz operation.

Refer to UM10204, I 2C-bus specification and user manual for detailed information on the

digital I2C communication protocol implementation. The FS5600 is designed to operate

as a slave device during I2C communication. The default I2C device address is set by the

OTP_I2C_ADD[2:0].

16 Thermal Protection

A thermal sensor placed at the center of the die monitors the temperature of the die and

triggers a shutdown if the die temperature exceeds 165 °C. When thermal shut-down is

entered, the TSD_I latch bit is set to notify the processor during subsequent power-up.

SW1 and SW2 regulators will immediately power down and GPIOs are asserted low

immediately upon entering the thermal shutdown state (no power down sequence).

All parameters are specified at TA = –40 °C to 125 °C, VIN = 12 V, VCC = 5.0 V, No

Load on regulators, Fsw = 2 MHz, and typical external component values, unless

otherwise noted. Typical values are specified at 25 °C, unless otherwise noted.
