MAX1385 Datasheet (Maxim Integrated Products) - (MAX1385 / MAX1386) Dual RF LDMOS Bias Controllers

MAX1385, (MAX1385 / MAX1386) Dual RF LDMOS Bias Controllers

The MAX1385/MAX1386 set and control bias conditions for dual RF LDMOS power devices found in cellular base stations.

Each device includes a high-side current-sense amplifier with programmable gains of 2, 10, and 25 to monitor LDMOS drain current over the 20mA to 5A range.

Two external diode-connecte

MAX1385 Features

* to minimize error over time, temperature, and supply voltage. The MAX1385/MAX1386 feature an I2C/SPI™-compatible serial interface. Both devices operate from a 4.75V to 5.25V analog supply (3.2mA supply current), a 2.7V to 5.25V digital supply (3.1mA supply current), and a 4.75V to 11.0V gate-drive s
