5 / 6 page Solid State Hall-effect Sensors Adjustable Hall-Effect Under-speed Detectors SS421 Series Honeywell • Sensing and Control 5 Table 5. Timing Characteristics (Note 1) (Required -25 °C to 105 °C [-13 °F to 221 °F] ambient) Parameter Min Max Unit Conditions Trip point range 1800 5200 PPM Ta = 25 °C [77 °F], Note 2 Trip point tolerance -16.0 16.0 % Variation from calculated value, Note 3 Trip point delay and power up delay Delayed version Non-delayed version 5.0 16.0 1.2 sec sec Ta = 25 °C [77 °F], 1800 to 5200 PPM Ta = +25 °C [77 °F], 1800 to 5200 PPM, Note 4 Delay set time tolerance -40 -4.0 40 4.0 % sec % of delay set time (whichever is smaller of the two sets) Passing delay fail to pass condition – 20 % % of delay set time, Note 5 External capacitor leakage coefficient – 0.05 – Note 6 Notes: 1. Over operating temperature and voltage range unless otherwise noted. Does not include R and C shifts over temperature. 2. Trip point is the frequency in PPM (pulses per minute) that causes the output to change state. An inverted output is low when the speed is greater than the trip point. 3. This is the accuracy required from unit to unit and includes R and C each varying ± 5% over speed, supply voltage, and temperature. 4. Trip point delay is the delay in output response to an input frequency below the trip point. The time delay is determined by the value of the external resistor and capacitor. Delayed version powers up in the passing condition. 5. Passing delay tolerance is based on delay set time. Its tolerance is proportional to delay set time tolerance. 6. Capacitor leakage coefficient is used to calculate leakage current in the following formula: leakage current = leakage coefficient x capacitance x capacitor voltage. Table 6. Latch Characteristics (Note 1) (Required -25 °C to 105 °C [-13 °F to 221 °F] ambient) Parameter Min Max Unit Conditions Latch voltage 3.5 2.0 4.5 4.5 V V At VS = 5.0, Note 2 Latch current – 1.0 mA Note 3 (SS421L only) Notes: 1. Over operating temperature and voltage range unless otherwise noted. External components must be connected between the output and the program/oscillator pin. 2. The open collector output can be used to drive external circuitry that applies a latching voltage to the program/oscillator pin to latch the IC output in the fail state. This latch mode is to be used only on products with delay set times greater than five seconds and with inverted output version of the SS421L. 3. Latching current is the sourcing current required of the applied external voltage to maintain the latch. Table 7. External R and C Characteristics (Note 1) (Required -25 °C to 105 °C [-13 °F to 221 °F] ambient) Parameter Min Max Unit Conditions External resistor – ±5 % Directly related to trip accuracy External capacitor – ±5 % Directly related to trip accuracy External capacitor leakage coefficient – 0.05 – Note 2 Notes: 1. Over operating temperature and voltage range unless otherwise noted. 2. Leakage coefficient is the external capacitor leakage current coefficient such that leakage current = leakage coefficient x capacitance x capacitor voltage. |
