Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and 2: The LTC7004 is tested under pulsed load conditions such that TJ TA. The LTC7004E is guaranteed to meet performance specifications from 0 C to 85 C. Specifications over the 40 C to 125 C operating junction temperature range are assured by design, characterization and correlation with statistical process controls. The LTC7004I is guaranteed over the 40 C to 125 C operating junction temperature range, the LTC7004H is guaranteed over the 40 C to 150 C operating junction temperature range and the LTC7004MP is tested and guaranteed over the 55 C to 150 C operating junction temperature range.

6 High junction temperatures degrade operating lifetimes; operating lifetime is derated for junction temperatures greater than 125 C. Note that the maximum ambient temperature consistent with these specifications is determined by specific operating conditions in conjunction with board layout, the rated package thermal impedance and other environmental factors. Note 3: The junction temperature (TJ, in C) is calculated from the ambient temperature (TA, in C) and power dissipation (PD, in Watts) according to the formula: TJ = TA + (PD JA), where JA is 45 C/ 4: This IC includes over temperature protection that is intended to protect the device during momentary overload conditions. The maximum rated junction temperature will be exceeded when this protection is active. Operation above the specified absolute maximum operating junction temperature may impair device reliability or permanently damage the 5: Dynamic supply current is higher due to the gate charge being delivered at the switching frequency.

CFor more information LTC7004 is designed to receive a ground-referenced, low voltage digital input signal, INP and quickly drive a high side N-channel power MOSFET whose drain can be up to 60V above ground. The LTC7004 is capable of driv-ing a 1nF load using a 12V bootstrapped supply voltage (VBST VTS) with 35ns of propagation delay and fast rise/fall times. The high gate drive voltage reduces external power losses associated with external MOSFET on-resistance.
