7 / 17 page ZL9101M 7 FN7669.1 January 26, 2011 Thermal Protection Threshold (Controller Junction Temperature) Factory setting – 125 – °C Configurable via I2C/SMBus -40 – 125 °C Thermal Protection Hysteresis – 15 – °C NOTES: 9. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design. 10. Parameters with TYP limits are not production tested unless otherwise specified. 11. Parameters are 100% tested for internal controller prior to module assembly. 12. VOUT measured at the termination of the FB+ and FB- sense points. 13. The device requires a delay period following an enable signal and prior to ramping its output. Precise timing mode limits this delay period to approximately 2ms, where in normal mode it may vary up to 4ms. 14. Precise ramp timing mode is only valid when using the EN pin to enable the device rather than PMBus enable. 15. The devices may require up to a 4ms delay following the assertion of the enable signal (normal mode) or following the de-assertion of the enable signal. 16. Factory setting for Power Good delay is set to the same value as the soft-start ramp time. 17. Nominal capacitance of logic pins is 5pF. Electrical Specifications VDD= 12 V, TA = -40°C to +85°C unless otherwise noted. Typical values are at TA = 25°C. Boldface limits apply over the operating temperature range, -40°C to +85°C.
