PACKAGE/ORDER INFORMATION

ELECTRICAL CHARACTERISTICS V

S = 13V to 20V, TA = 25°C (Note 1), unless otherwise noted.

The q denotes the specifications which apply over the full operating

temperature range.

Note 1: Both VS pins (10, 14) must be connected together, and both

ground pins (1, 5) must be connected together.

Note 2: For junction temperatures greater than 110

°C, a minimum

load of 1mA is recommended.

Note 3: The other channel is programmed to the 0V mode (XEN0 =

XEN1 = 0V) during this test.

Note 4: The VCC sense threshold voltage tests are performed

independently.

Note 5: The VPPVALID tests are performed independently.

TJMAX = 125°C, θJA = 100°C/ W
