Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and 2: The LTC7001 is tested under pulsed load conditions such that TJ TA.

6 The LTC7001E 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 LTC7001I is guaranteed over the 40 C to 125 C operating junction temperature range, the LTC7001J is guaranteed over the 40 C to 150 C operating junction temperature range, the LTC7001H is guaranteed over the 40 C to 150 C operating junction temperature range and is tested at 150 C, the LTC7001MP is tested and guaranteed over the 55 C to 150 C operating junction temperature range. 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.

7 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. See Applications 6: Do not apply a voltage or current source to these pins. They must be connected to capacitive loads only; otherwise permanent damage may 7: Total supply current is the sum of the current into the VCC and TS GFor more information PERFORMANCE CHARACTERISTICST otal Supply Current with External FET ON vs TS VoltageDriver On Resistance vs VBST-TS VoltageInput Threshold Voltage vs VCC Supply VoltageCharge Pump No-Load Output Voltage vs VTSC harge Pump Load RegulationCharge Pump Output Current vs VTSTA = 25 C, unless otherwise = 5 VVCC = 12 VVTS (V) (mA)7001 G01 VCCUV = 0 VTGUPTGDNVBST-TS (V)36912150123456 RDSON ( )7001 G02 VIN = VCCRISINGFALLINGVCCVOLTAGE (V) VOLTAGE (V)7001 G03 IBST = 0 AVCC = 4 VVCC = 5 VVCC = 6 VVCC = 7 VVCC 8 VVTS (V)0510152002468101214 VBST - VTS (V)7001 G04 VCC = 7 VVBST-TS = 10V25 C150 CVTS (V)0285684112140 45 35 25 15 55 IBST ( A)7001 G6 VCC = 4 VVTS = 4 VVTS = 6 VVTS = 8 VVTS = 10 VVTS = 12 VIBST ( A)

INP has an internal 1M pull-down to GND to keep TGDN pulled to TS during startup (Pin 5): Overvoltage Lockout Input. Connect to the input supply through a resistor divider to set the lockout level. A voltage on this pin above causes TGDN to be pulled to TS.
