51992 CURRENT DRIVER DSCC DWG #5962-87617 (Replacement for DH0006) Features: Applications: • • • • • • • • • • Operation from a Single +10V to +45V Power Supply Low Standby Power Dissipation of only 35mW for 28V Power Supply 1.5A, 50ms on, 1 sec off, Pulse Capability Meets MIL-PRF-38534 Class H Requirements Environmentally Screened per MIL-STD-883 Mii HYBRID MICROELECTRONICS PRODUCTS DIVISION Military / High Reliability Systems Aircraft Engine Environment Controls – High Current Pulse Applications Lamp Driver DESCRIPTION The 51992 is a high voltage current driver with DTL compatible TTL logic levels and drive a load up to 400 mA at 28V. Should additional gating be required, AND inputs are provided along with an Expander connection. The addition of an external capacitor provides control of the rise and fall times of the output in order to decrease cold lamp surges or to minimize electromagnetic interference if long lines are driven. Device can be gated On and Off at normal inputs or at pin 8. Since one side of the load is normally grounded there is less likelihood of false turn-on due to an inadvertent short in the drive line. Meets the requirements of SMD 5962-87617.
