PIN I/O DESCRIPTION
NAME NO.
CT 1 I/O Timing capacitor connection
This terminal sets the RESET output pulse duration (tpo). It is connected internally to a 15-µA constant-current source. There is a limit on the switching speed of internal elements; even if CT is set to 0, response speeds remain at approximately 5 to 10 µs.
If CT is open, the device can be used as an adjustable-threshold noninverting comparator. If CT is low, the internal output-stage comparator is active, and the RESET output transistor is on. An external voltage must not be applied to this terminal due to the internal structure of the device. Therefore, drive the device using an open-collector transistor, FET, or tri-state buffer (in the low-level or high-impedance state).
GND 4 — Ground
Keep this terminal as low impedance as possible to reduce circuit noise.
NC 3, 6, 7 — No internal connection.
RESET 8 O Reset output
This terminal can be connected directly to a system that resets in the active-low state. A pullup resistor usually is required because the output is an npn open-collector transistor. An additional transistor should be connected when the active-high reset or higher output current is required.
SENSE 2 I Voltage sense
This terminal has a threshold level of 500 mV. The sense voltage and hysteresis can be set at the same time when the two voltage-dividing resistors are connected. The reference voltage is temperature compensated to inhibit temperature drift in the threshold voltage within the operating temperature range.
VCC 5 — Power supply
This terminal is used in an operating-voltage range of 1.8 V to 40 V.
