CURRENT LIMITATION
  • Output current internally limited
  • Products like VN808, VN330SP, L6375 etc.
  • Current limitation externally programmable
  • L6377 0.1A lt Isc lt 1A
  • L6370 0.3A lt Isc lt 3A
  • Non dissipative short circuit protection
  • L6376 Ton and Toff external independently
    programmable
  • L6370/7 Ton ext. progr. Toff 64Ton



6
OPEN LOAD DETECTION
  • The diagnostics is active when the load is
    disconnected

7
DIAGNOSTICS
DC Supply bus
to mP
Diag
GND
  • Open Drain Diagnostic for Wired OR
  • More diagnostic outputs and one opto-coupler can
    be used to signal the device(s) status

GND






8
HIGH NOISE IMMUNITY INPUT STAGE
  • High noise immunity 200mV hysteresis
  • High impedance
  • Multi-Standard Link
  • Operative range
  • 0 to 40V for L6376
  • -7 to 15V for L6370/7/5



9
EMC Compliance
  • IEC 61000-4-4 Burst test Level 4 (4kV)
    Input/Output ports Power supply lines
  • IEC 61000-4-5 Surge test Level 3 (2kV)
  • Output ports Power supply lines by
  • IEC 6000-4-6 Conducted disturbances Level 3 (10V)
    Input/Output ports Power supply lines by

Transil diode
Capacitor 10nF on output channel
