L8567 SLIC for
Electrical Characteristics
Minimum and maximum values are testing requirements in the temperature range of 25 °C to 85 °C and battery
range of –35 V to –65 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 6 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
= V
DD
= 5.0 V, V
BAT1
= –48 V,
V
BAT2
= –25.5 V.
Table 4. Power Supply
1. This parameter is not tested in production. It is guaranteed by design and device characterization.
2. This is the total power drawn from the power supplies. If a power resistor is not used, the total power is dissipated by the SLIC through the
package. If a power resistor is used, the power is shared by the resistor and the SLIC.
