LM5067MM-1

The LM5067MM-1 is negative hot swap controller provides intelligent control of the power supply connections during insertion and removal of circuit cards from a live system backplane or other "hot" power sources. The device provides in-rush current control to limit system voltage droop and transients.

The features of LM5067MM-1 can be summarized as:(1)Wide operating range: -9V to -80V; (2)In-rush current limit for safe board insertion into live power sources; (3)Programmable maximum power dissipation in the external pass device; (4)Adjustable current limit; (5)Circuit breaker function for severe over-current events; (6)Adjustable under-voltage lockout (UVLO) and hysteresis; (7)Adjustable over-voltage lockout (OVLO) and hysteresis; (8)Initial insertion timer allows ringing and transients to subside after system connection; (9)Programmable fault timer avoids nuisance trips; (10)Active high open drain POWER GOOD output; (11)Available in latched fault and automatic restart versions.

The absolute maximum ratings of LM5067MM-1 are:(1)Current into VCC (100 s pulse):100 mA; (2)OUT, PGD to VEE:-0.3V to 100V; (3)UVLO, OVLO to VEE:-0.3V to 17V; (4)SENSE to VEE:-0.3V to +0.3V; (5)ESD Rating,Human Body Model:2kV; (6)Storage Temperature:-65°C to +150°C; (7)Junction Temperature:+150°C; (8)Current into VCC:2 mA (min); (9)OUT Voltage above VEE:0V to 80V; (10)PGD Off Voltage above VEE:0V to 80V; (11)Junction Temperature:-40°C to +125°C.
