LM5064PMHE/NOPB

The Texas Instruments LM5064PMHE/NOPB is an active hot swap controller specifically designed for negative voltage systems, supporting input voltages from -10V to -80V. This device is housed in a 28-HTSSOP package and features surface mount technology.

Key electrical specifications include a typical quiescent current of 6 mA and a maximum of 8 mA. The controller offers programmable current limit thresholds of 26 mV or 50 mV, with power limiting capabilities. It provides real-time monitoring of V_IN, V_OUT, I_IN, P_IN, and V_AUX with 12-bit resolution and a 1 kHz sampling rate. Power measurement accuracy is rated at ±4.5% over temperature.

This hot swap controller integrates several protection features, including configurable circuit breaker protection for hard shorts, configurable under-voltage and over-voltage protection, and thermal shutdown. It also supports features like adjustable OVLO, adjustable soft start, current monitoring, fault output, overcurrent protection, PMBus communication, a power good signal, short circuit protection, and adjustable UVLO. The fault response can be configured for auto-retry or latch-off, and overvoltage response is a cut-off.

The operating temperature range for the LM5064PMHE/NOPB is -40°C to 125°C. Its primary application is in -48V systems, making it suitable for power management and protection in various industrial and telecommunications equipment.
