PIN CONFIGURATION  
The dissipation pad for the USP-6C  
package should be solder-plated in  
reference mount pattern and metal  
masking to enhance mounting strength  
and heat release. If the pad needs to be  
connected to other pins, it should be  
connected to the VSS (No. 5) pin.

Diodes inside the circuits are ESD protection diodes and parasitic diodes.  
BASIC OPERATION  
The error amplifier compares the internal reference voltage with the voltage divided by resistors R1, R2, and R3  
connected to the VIN pin of the IXD5121 – 4 (see block diagrams above). The resulting output signal from the error  
amplifier activates the watchdog logic, delay circuit, and the output driver. When the VIN voltage becomes equal or  
ꢀꢀꢀꢀꢀꢀꢀꢀꢀ  
below detect voltage, the RESET output goes from high to low state.  
ꢀꢀꢀꢀꢀꢀꢀꢀꢀ  
ꢊꢋꢌꢋꢍ Pin Output Signal  
ꢀꢀꢀꢀꢀꢀꢀꢀꢀ  
The RESET pin output goes from high to low state whenever the VIN pin voltage becomes equal or below the detect  
ꢀꢀꢀꢀꢀꢀꢀꢀꢀ  
voltage. The RESET pin remains in low state during the Release Delay Time tDR after the VIN voltage becomes equal  
ꢀꢀꢀꢀꢀꢀꢀꢀꢀ  
or above the release voltage. When Release Delay Time tDR elapsed, the RESET pin goes into high state, if no rising  
or falling signals appear on the WD pin within the watchdog timeout period.  
Hysteresis  
When the internal comparator output is high, the N-channel MOSFET transistor connected in parallel to R3 turns  
ON, activating the hysteresis circuit. The difference between the release and detect voltages represents the  
hysteresis width, as shown by the following calculations:  
VDFL (detect voltage) = (R1+R2+R3) x Vref / (R2+R3)  
VDR (release voltage) = (R1+R2) x Vref / (R2)  
VHYS (hysteresis width) =VDR-VDFL (V) = VDFL x 0.05 (typical)  
Watchdog (WD) Pin  
A watchdog timer allows detect malfunction or “runaway” of the microprocessor. If no rising or falling signals from  
ꢀꢀꢀꢀꢀꢀꢀꢀꢀ  
the microprocessor appears at WD pin within the Watchdog Timeout period, the RESET pin output remains in the  
ꢀꢀꢀꢀꢀꢀꢀꢀꢀ  
low state during the Release Delay Time (tDR), and thereafter the RESET pin goes to high state.  
The WD pin has an internal pull-down resistor connected to the VSS. When the watchdog pin is open, or connected  
to VSS, and watchdog is active, a reset signal comes out after the Watchdog Timeout period (tWD), which is available  
at 1.6 s, 800 ms, 400 ms, 200 ms, 100 ms, and 50 ms value.  
EN Pin  
If the watchdog function is not used, the EN pin should be in logic low state. This disables watchdog function only,  
while the detect voltage circuit remains operational.  
The EN pin should be logic high to activate watchdog function. The watchdog function activates immediately, when  
the EN pin voltage goes from low to high level and the input voltage is higher than the release voltage. (Refer to the  
TIMING DIAGRAM 1-Ç.)  
ꢀꢀꢀꢀꢀꢀꢀꢀꢀ  
ꢀꢀꢀꢀꢀꢀꢀꢀꢀ  
However, if the EN pin voltage goes high, when the RESET pin is in detection state, the RESET pin output maintains  
this state during the Release Delay Time (tDR) after VIN becomes equal or above VDR. (Refer to the TIMING  
DIAGRAM 1-Å.)

A protection diode is connected between the EN and VIN pins. If the EN pin voltage exceeds VIN, the current will  
flow to VIN through the diode. To avoiding any damage to the IC, EN voltage should not exceed maximum ratings  
(VSS -0.3 ~ VIN +0.3 V).

VIN through the diode. To avoiding any damage to the IC, EN pin voltage should not exceed maximum ratings (VSS

Release Delay Time  
Release Delay Time (tDR) is the time from the moment, when the VIN pin becomes equal or above the release  
ꢀꢀꢀꢀꢀꢀꢀꢀꢀ  
voltage VDR, until the RESET pin output changes state. When the Watchdog Timeout period expires with no rising  
ꢀꢀꢀꢀꢀꢀꢀꢀꢀ  
signal applied to the WD pin, the same Release Delay Time (tDR) should elapse, until the RESET pin output changes  
state. Five release delay times (tDR) are available at 400ms, 200ms, 100ms, 50ms, and 3.13ms.  
Detect Delay Time  
Detect Delay Time (tDF) is the time from the moment, when the VIN pin voltage becomes equal or below the detect  
ꢀꢀꢀꢀꢀꢀꢀꢀꢀ  
voltage until the RESET pin output goes into the detection state.

TYPICAL APPLICATION CIRCUIT

Resistors RPL2 are used with IXD5121 and IXD5123 series only.  
LAYOUT AND USE CONSIDERATIONS  
1. The IC may malfunction if absolute maximum ratings are exceeded.  
2. High impedance VIN power supply may cause IC malfunction, if VIN voltage falls below minimum operating level due  
ꢀꢀꢀꢀꢀꢀꢀꢀꢀ  
current consumption, when IC output changes state. In addition, the RESET pin voltage at “High” state reflects every  
variations of VIN voltage.  
3. High impedance VIN power supply may cause IC oscillations, if voltage drop at power supply’s internal resistance  
exceeds IC hysteresis.  
4. Note that a rapid and high amplitude fluctuation of the VIN pin voltage, as well as a power supply noise, may cause a  
wrong IC operation. The capacitor of 0.22 µF between VIN and GND pins should be used to minimize noise impact.  
5. Watchdog Timer has a dead time of less than 900 µs after activation. Signals applied to WD pin during this dead time  
are ignored (see Timing Diagram 4 above).  
ꢀꢀꢀꢀ  
6. Internal pull-up/ down resistors at EN/EN pins of the IXD5122/4 series allows use watchdog function with these  
ꢀꢀꢀꢀ  
pins open. IXD5121/23 series require EN/EN pins to be pulled up/down respectively to activate watchdog  
function.
