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 5 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 VCC = 5.0 V, VEE = –5.0 V, VBAT1 =
–48 V, VBAT2 = –25.5 V, unless otherwise noted.
