Description
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.
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 supply (4.5mA supply current). The MAX1385/MAX1386 are available in a 48-pin thin QFN package. Features.
- Integrated High-Side Drain Current-Sense PGA with Gain of 2, 10, or 25.
- ±0.5%.
