Table 45.

Static characteristics

Minimum and maximum values are specified for the following conditions: VBAT = 5.5 V to 40 V, VEN = 4.5 V to 5.5 V,

VVCC = 4.5 V to 5.5 V and Tj = 40 C to +175 C[1]. All voltages are defined with respect to ground, positive currents flow into

the IC. Typical values are given at VVIN = 40 V, VEN = 5 V, VVCC = 5 V and Tj =25 C unless otherwise specified.
