LM25066IA
Overview
While the LM25066I/A is functionally similar to the LM25066/A, the LM25066I/A is fully compliant to Intel Node Manager 2.0, 2.5 and adds the READ_EIN energy accumulator feature. The LM25066I/A combines a high-performance hot-swap controller with a PMBus 1.2™ compliant SMBus/I2C interface to accurately measure, control and protect the electrical operating conditions of critical systems.
- 2 Fully Node Manager 2.0 and 2.5 Compliant with I2C/SMBus interface and PMBus™ compliant command structure
- Input voltage range: 2.9V to 17V
- Programmable 25mV or 46mV current limit threshold
- Read_EIN accurately measures true input power via simultaneous sampling
- Configurable circuit breaker protection for hard shorts
- Configurable under- and over-voltage lockouts with hysteresis
- Real time monitoring of VIN, VOUT, IIN, PIN, VAUX with 12-bit resolution and 1 kHz sampling rate
- Current measurement accuracy: ±1% (LM25066IA) and Power measurement accuracy: ±2.0% (LM25066IA) over temperature
- Averaging of VIN, IIN, PIN, and VOUT over programmable interval ranging from 0.001 to 4 seconds
- Programmable WARN and FAULT thresholds with SMBA notification
