Manufacturer:TOSHIBA Description:Chip Enable (CEN) input pin, when low, disables both outputs (OUT1 and OUT2) and places the device in a sleep mode reducing the bias current required from VDD and VPwr. A falling edge of CEN causes OUT1 and OUT2 to rapidly turn OFF. A falling edge of CEN should precede any VDD shutdown to allow time OUT1 and OUT2 to be disabled. When CEN is low, INTerrupt (INT) and STATus 1 and 2 (STAT1C2) will be triCstated (high impedance). The CEN pin can also be used for powerCon reset and under voltage lockout to disable the outputs for power supply voltages less than 4.5 V. CEN is a dependent input from the system microcontroller unit (MCU) or some other integrated circuit. It has an internal pullCup resistor to VDD affording a floating pin to be interpreted as a logic high. RpullCup is greater than 50 kΩ. If used externally, this pin should be connected to VDD. |
