Electrical Characteristics
Minimum and maximum values are testing requirements in the temperature range of 25 °C to 85 °C and battery
range of –24 V to –70 V. These minimum and maximum values are guaranteed to –40 °C based on component
simulations and design verification of samples, but devices are not tested to –40 °C in production. The test circuit
shown in Figure 4 is used, unless otherwise noted. Positive currents flow into the device.
Typical values are characteristics of the device design at 25 °C based on engineering evaluations and are not part
of the test requirements. Supply values used for typical characterization are V
CC
= 5.0 V, V
BAT
= –48 V, unless oth-
erwise noted.
Table 4. Power Supply
1. This parameter is not tested in production. It is guaranteed by design and device characterization.
2. Careful thermal design as a function of maximum battery, loop length, maximum ambient temperature package thermal resistance, airflow,
PCB board layers, and other related parameters must ensure that thermal shutdown temperature is not exceeded under normal use condi-
tions.
3. Airflow, PCB board layers, and other factors can greatly affect this parameter.
