This document describes two errors of MAXQ612 revision B1 chip. The first error is that when the internal oscillator (PLL) is used in divide-by-4 mode as system clock, the watchdog timer reset will lock the IC, and a power cycle is required to recover. The second error is that flash word programming and page erase operations do not complete successfully when invoked with clock divide-by-2, divide-by-4, or divide-by-8 modes active.

MAX4854 is a 4-way single-pole/single-throw switch that is powered by a single supply of +2V to +5.5V and can handle signals that are greater than the supply swing. The switch has a low on-resistance and low on-capacitance, making it ideal for data signal switching. For over-range applications, signals that are greater than the positive supply (up to +5.5V) can still pass through the switch without distortion. MAX4854 is housed in a space-saving, 16-pin, 3mm x 3mm thin QFN package and operates in an extended temperature range of -40°C to +85°C.

MAX6641 is a temperature sensor and fan controller that accurately measures the temperature of its own die and the temperature of a remote PN junction. The device uses a 2-wire serial interface to report temperature values in digital form. The temperature data controls the PWM output signal to adjust the speed of the cooling fan. This allows for minimal noise when the system operates at low temperatures, but provides maximum cooling capacity when power consumption increases. The device also features an over-temperature alert output for generating interrupt, slowdown, or shutdown signals. MAX6641 operates in a supply voltage range of 3.0V to 5.5V, with a typical supply current of 500mA. The MAX6641 is available in a small 10-pin µMAX package and operates in an automotive temperature range of -40°C to +125°C.

The MAX13442E/MAX13444E are fault-protected RS-485 and J1708 transceivers that feature ±80V protection from signal faults on communication bus lines. The MAX13442E/MAX13444E feature a reduced slew-rate driver that minimizes EMI and reflections, allowing error-free transmission up to 250kbps. The MAX13443E driver can transmit up to 10Mbps. The high-speed MAX13443E RS-485 tranceiver features ±60V protection from signal faults on communication bus lines. These transceivers feature foldback current limit. Each device contains one differential line driver with three-state output and one differential line receiver with three-state input. The 1/4-unit-load receiver input impedance allows up to 128 transceivers on a single bus. The devices operate from a 5V supply. True fail-safe inputs guarantee a logic-high receiver output when the receiver inputs are open, shorted, or connected to an idle data line. Hot-swap circuitry eliminates false transitions on the data bus during circuit initialization or connection to a live backplane. Short-circuit current-limiting and thermal-shutdown circuitry protect the driver against excessive power dissipation, and on-chip ±15kV ESD protection eliminates costly external protection devices. The MAX13442E/MAX13443E/MAX13444E are available in an 8-pin SO package and are specified over the automotive temperature range.
