The GATE1 pin is held low by an internal undervoltage lockout circuit until V CC1 and VCC2 exceed their respective undervoltage lockout threshold of 2.165V and 0.8V. This input is protected up to 20V. 1 1 VCC2 Positive Supply (Input), Channel 2: The GATE2 pin is held low by an internal undervoltage lockout circuit until V CC1 and VCC2 exceed their respective undervoltage lockout threshold of 2.165V and 0.8V. This input must be in the range of 1.0V to 13.2V and less than or equal to V CC1. This input is protected up to 20V. 2, 15 2, 23 SENSE2, SENSE1 Circuit Breaker Sense (Inputs): A resistor between this pin and VCC1 and VCC2 sets the current limit threshold for each channel. Whenever the voltage across either sense resistor exceeds the slow trip current limit threshold (V TRIPSLOW), the GATE voltage is adjusted to ensure a constant load current. If V TRIPSLOW (50mV) is exceeded for longer than time period t OCSLOW, then the circuit breaker is tripped and both GATE outputs are immediately pulled low. If the voltage across either sense resistor exceeds the fast trip circuit breaker threshold, V TRIPFAST, at any point due to fast, high amplitude power supply faults, then both GATE outputs are immediately brought low without delay. To disable the circuit breaker for either channel, the SENSE and VCC pins can be tied together. The default V TRIPFAST for either device is 100mV. Other fast trip thresholds are available: 150mV, 200mV, or OFF (V TRIPFAST disabled). Please contact factory for availability of other options. 6 8 ON Enable (Input): Active High. The ON pin, an input to a Schmitt-triggered comparator used to enable/disable the controller, is compared to a 1.235V reference with 25mV of hysteresis. When a logic high is applied to the ON pin (V ON > 1.235V), a start-up sequence begins when the GATE1 and GATE2 pins begin ramping up towards their final operating voltage. When the ON pin receives a logic low signal (V ON < 1.21V), the GATE pins are grounded and /FAULT remains high if both inputs are above their respective UVLO thresholds. The ON pin must be low for at least 20 µs in order to initiate a start-up sequence. Additionally, toggling the ON pin LOW to HIGH resets the circuit breaker. |
