The MABC-11040 is a flexible bias generation and temperature supervision IC.
The MABC-11040 contains four highly integrated, temperature-controlled DACs that support a negative output range from -6V to 0V and are capable of handling large output currents. The four DACs can be programmed independently by four separate user-defined temperature-to-voltage functions stored in the internal EEPROM, allowing any temperature effects to be corrected without additional external circuitry. Each output can be switched to the load individually through the use of dedicated control pins.
The MABC-11040 provides bias sequencing for safe power up and power down. The drain voltage may be applied with a control signal via the internal drain bias control once the IC has powered up and correct biasing has been asserted.
Once powered up, the device operates autonomously, without intervention from the system controller, providing a plete solution for setting and pensating bias voltages and currents in control applications. Additionally, the device supports up to four thermistors placed closely to the PAs for more accurate temperature reading.
The digital interface allows control and monitoring of all four Low side drivers, gate current, and temperature of the PA....
