LSF0102 / VIH and VIL of EN pin

Other Parts Discussed in Thread: LSF0102

Hi,

LSF0102 has EN pin but VIH and VIL are not specified in electrical characteristics. Can you provide these value? Now my customer plan to control EN pin by separated control signal Vref_B voltage.

Best Regards,

Sonoki / Japan Disty

    Section 9.2.1.1.1 says:

    Vref_B and VI(EN) are recommended to be at 1.0 V higher than Vref_A for best signal integrity.

    There's nothing said directly about the low level. But the datasheet recommends a 200 kΩ pull-up resistor for EN, which implies that EN puts only a very small load on whatever is connected to it. This implies that any CMOS output should be fine.
