AUTOMOTIVE, 125°C OPERATION,
36 V INPUT, 50 mA VOLTAGE TRACKER
WITH REVERSE CURRENT PROTECTION
Rev.1.3_00
© ABLIC Inc., 2021-2022
This IC, developed by using high-withstand voltage CMOS process technology, is a voltage tracker with a reverse current
protection function, which has high-withstand voltage and low current consumption.
Since the maximum operating voltage is as high as 36 V and the current consumption is as low as 30 μA typ., it
contributes to the reduction of standby current.
This IC operates stably due to the internal phase compensation circuit so that users are able to use low ESR ceramic
capacitor as the output capacitor.
This IC includes an overcurrent protection circuit that prevents the load current from exceeding the current capacity of the
output transistor and a thermal shutdown circuit that prevents damage because of overheating.
Due to the built-in reverse current protection function, the reverse current flowing from the VOUT pin to the VIN pin can be
controlled as the small value −5 μA min. Therefore, IC protection diode is not needed.
ABLIC Inc. offers a "thermal simulation service" which supports the thermal design in conditions when our power
management ICs are in use by customers. Our thermal simulation service will contribute to reducing the risk in the thermal

Caution The above connection diagram and constants will not guarantee successful operation. Perform
thorough evaluation using an actual application to set the constants.
Condition of Application
Input capacitor (CIN):
Output capacitor (CL):
A ceramic capacitor with capacitance of 1.0 μF or more is recommended.
A ceramic capacitor with capacitance of 1.0 μF to 1000 μF is recommended.
Caution Generally, in a voltage tracker, an oscillation may occur depending on the selection of the external
parts. Perform thorough evaluation including the temperature characteristics with an actual
application using the above capacitors to confirm no oscillation occurs.
Selection of Input Capacitor (CIN) and Output Capacitor (CL)
This IC requires CL between the VOUT pin and the VSS pin for phase compensation. The operation is stabilized by a
ceramic capacitor with capacitance of 1.0 μF to 1000 μF over the entire temperature range. When using an OS
capacitor, a tantalum capacitor or an aluminum electrolytic capacitor, the capacitance also must be 1.0 μF to 1000 μF.
However, an oscillation may occur depending on the equivalent series resistance (ESR).
Moreover, this IC requires CIN between the VIN pin and the VSS pin for a stable operation.
Generally, an oscillation may occur when a voltage tracker is used under the condition that the impedance of the power
supply is high.
Note that the output voltage transient characteristics varies depending on the capacitance of CIN and CL and the value
of ESR.
Caution Perform thorough evaluation including the temperature characteristics with an actual application to
select CIN and CL.

Basic operation
Figure 13 shows the block diagram of this IC to describe the basic operation.
The error amplifier compares the output voltage (VOUT) with the ADJ / EN pin voltage (VADJ / EN).
The error amplifier controls the output transistor to keep VOUT equal to VADJ / EN without being affected by the input
voltage (VIN), that is, the tracking operation is performed.

2.
Output transistor
In this IC, a low on-resistance P-channel MOS FET is used between the VIN pin and the VOUT pin as the output
transistor. In order to maintain the tracking operation of VADJ / EN and VOUT, the on-resistance of the output transistor
varies appropriately according to the output current (IOUT).
Also, the reverse current prevention transistor is connected in series with the output transistor.
3.
ADJ / EN pin
The ADJ / EN pin controls the internal circuit and the output transistor in order to start and stop the tracker.
When the ADJ / EN pin is set to ON (VADJ / EN ≥ VADJH), the tracking operation starts and VOUT is adjusted so that it
becomes equal to VADJ / EN.
When the ADJ / EN pin is set to OFF, the internal circuit stops operating and the output transistor between the VIN
pin and the VOUT pin is turned off, reducing current consumption significantly.
The ADJ / EN pin is internally pulled down to the VSS pin in the floating status, so the VOUT pin is set to the VSS
level.

Overcurrent protection circuit
This IC includes an overcurrent protection circuit which having the characteristics shown in "1. Output voltage
vs. Output current (When load current increases) (Ta = +25°C)" in " Characteristics (Typical Data)", in order
to limit an excessive output current and overcurrent of the output transistor due to short-circuiting between the
VOUT pin and the VSS pin.
When the load current increases and reaches the limit current (ILIM), the overcurrent protection circuit operates, and
the output current is limited based on ILIM. When the output is short-circuited (the VOUT pin is shorted to the VSS
pin), the output current is limited to short-circuit current (Ishort). ILIM and Ishort are internally set at 180 mA typ.
This IC restarts the tracking operation over VOUT and VADJ / EN when the output transistor is released from the
overcurrent status.
Caution
5.
This overcurrent protection circuit does not work as for thermal protection. If this IC long keeps
short circuiting inside, pay attention to the conditions of input voltage and load current so that,
under the usage conditions including short circuit, the loss of the IC will not exceed power
dissipation of the package.
Thermal shutdown circuit
This IC has a built-in thermal shutdown circuit to limit overheating. When the junction temperature increases to
175°C typ., the thermal shutdown circuit becomes the detection status, and the tracking operation is stopped. When
the junction temperature decreases to 165°C typ., the thermal shutdown circuit becomes the release status, and the
tracking operation is restarted.
If the thermal shutdown circuit becomes the detection status due to self-heating, the tracking operation is stopped
and VOUT decreases. For this reason, the self-heating is limited and the temperature of the IC decreases. The
thermal shutdown circuit becomes release status when the temperature of the IC decreases, and the tracking
operation is restarted, thus the self-heating is generated again. Repeating this procedure makes the waveform of
VOUT into a pulse-like form. This phenomenon continues unless decreasing either or both of VIN and IOUT in order to
reduce the internal power consumption, or decreasing the ambient temperature. Note that the product may suffer
physical damage such as deterioration if the above phenomenon occurs continuously.
Caution
If a large load current flows during the restart process of the tracking operation after the thermal
shutdown circuit changes to the release status from the detection status, the thermal shutdown
circuit becomes the detection status again due to self-heating, and a problem may happen in the
restart of the tracking operation. A large load current, for example, occurs when charging to the
CL whose capacitance is large.
Perform thorough evaluation including the temperature characteristics with an actual application
to select CL.

Reverse current protection function
The reverse current protection function compares values of VIN and VOUT, and prevents the current from flowing to
the VIN pin from the VOUT pin.
During the reverse current protection mode, the reverse current detection circuit turns off the reverse current
protection transistor between the VIN pin and the output transistor and blocks the reverse current from the VOUT
pin.
In the case of VOUT − VIN < VREVD, this IC is in normal operation mode (refer to Figure 14). The reverse current
protection mode is detected when VOUT − VIN ≥ VREVD (refer to Figure 15). In order to insure the stable operation,
there is also a hysteresis for detection and release of the reverse current protection mode. Therefore, the reverse
current protection mode is released when VOUT − VIN ≤ VREVR.
The reverse current protection function also operates when the ADJ / EN pin is set to OFF level.

Precautions
• Generally, when a voltage tracker is used under the condition that the load current value is small (0.1 mA or less),
the output voltage may increase due to the leakage current of an output transistor.
• Generally, when a voltage tracker is used under the condition that the temperature is high, the output voltage may
increase due to the leakage current of an output transistor.
• Generally, when the ADJ / EN pin of a voltage tracker is used under the condition of OFF, the output voltage may
increase due to the leakage current of an output transistor.
• Generally, when a voltage tracker is used under the condition that the impedance of the power supply is high, an
oscillation may occur. Perform thorough evaluation including the temperature characteristics with an actual
application to select CIN.
• Generally, in a voltage tracker, an oscillation may occur depending on the selection of the external parts. The
following use conditions are recommended in this IC, however, perform thorough evaluation including the
temperature characteristics with an actual application to select CIN and CL.
Input capacitor (CIN): A ceramic capacitor with capacitance of 1.0 μF or more is recommended.
Output capacitor (CL): A ceramic capacitor with capacitance of 1.0 μF to 1000 μF is recommended.
• Generally, in a voltage tracker, the values of an overshoot and an undershoot in the output voltage vary depending
on the variation factors of input voltage start-up, input voltage fluctuation and load fluctuation etc., or the
capacitance of CIN or CL and the value of the equivalent series resistance (ESR), which may cause a problem to the
stable operation. Perform thorough evaluation including the temperature characteristics with an actual application to
select CIN and CL.
• Generally, in a voltage tracker, an overshoot may occur in the output voltage momentarily if the input voltage steeply
changes when the input voltage is started up or the input voltage fluctuates etc. Perform thorough evaluation
including the temperature characteristics with an actual application to confirm no problems happen.
• Generally, in a voltage tracker, if the VOUT pin is steeply shorted with GND, a negative voltage exceeding the
absolute maximum ratings may occur in the VOUT pin due to resonance phenomenon of the inductance and the
capacitance including CL on the application. The resonance phenomenon is expected to be weakened by inserting a
series resistor into the resonance path, and the negative voltage is expected to be limited by inserting a protection
diode between the VOUT pin and the VSS pin.
• If the input voltage is started up steeply under the condition that the capacitance of CL is large, the thermal
shutdown circuit may be in the detection status by self-heating due to the charge current to CL.
• Make sure of the conditions for the input voltage, output voltage and the load current so that the internal loss does
not exceed the power dissipation.
• Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic
protection circuit.
• When considering the output current value that this IC is able to output, make sure of the output current value
specified in Table 6 in " Recommended Operation Conditions" and footnote *1 of the table.
• Wiring patterns on the application related to the VIN pin, the VOUT pin and the VSS pin should be designed so that
the impedance is low. When mounting CIN between the VIN pin and the VSS pin and CL between the VOUT pin and
the VSS pin, connect the capacitors as close as possible to the respective destination pins of this IC.
• In the package equipped with heat sink of backside, mount the heat sink firmly. Since the heat radiation differs
according to the condition of the application, perform thorough evaluation with an actual application to confirm no
problems happen.
• ABLIC Inc. claims no responsibility for any disputes arising out of or in connection with any infringement by products
including this IC of patents owned by a third party.
