IXYS MX844
The MX844 is a fully integrated subsystem that measures temperature plus differential current and voltage. The differential sense amplifier is optimized to measure very small positive or negative voltages near ground for low side bi-directional sensing. An on-chip voltage regulator enables the MX844 to operate over a wide input voltage range of 4.5 to 40 volts.| Part No. | MX844 |

DESCRIPTION
: An internal temperature sensor measures ambient temperature with 2.5°C accuracy. Current and voltage measurements are made differentially through a four input multiplexer connected to a programmable gain fully differential sense amplifier. A dual slope ADC converts the temperature sensor or sense amplifier outputs to a 12-bit digital word that includes 3 ½ digits plus sign. The input multiplexer channel and programmable gain amplifier range may be changed between ADC conversions. Controller interrupt or over-voltage/over-current signals may be generated by a pair of 12-bit digital comparators configured as a window comparator or simple threshold detection function. The serial port supports standard 4-wire synchronous serial data, or asynchronous serial “talk-only” data, and is compatible with most 3.3V and 5V microcontrollers. Wide Input Supply Range: 4.5V to 40V P...
