To all our customers
Regarding the change of names mentioned in the document, such as Hitachi
Electric and Hitachi XX, to Renesas Technology Corp.
The semiconductor operations of Mitsubishi Electric and Hitachi were transferred to Renesas
Technology Corporation on April 1st 2003. These operations include microcomputer, logic, analog
and discrete devices, and memory chips other than DRAMs (flash memory, SRAMs etc.)
Accordingly, although Hitachi, Hitachi, Ltd., Hitachi Semiconductors, and other Hitachi brand
names are mentioned in the document, these names have in fact all been changed to Renesas
Technology Corp. Thank you for your understanding. Except for our corporate trademark, logo and
corporate statement, no changes whatsoever have been made to the contents of the document, and
these changes do not constitute any alteration to the contents of the document itself.

Undervoltage lockout (UVL)
Error amplifier
Vref overvoltage protection (OVP)
Features
Wide supply voltage range: 3.9 V to 40 V*
Maximum operating frequency: 600 kHz
Able to drive a power MOS FET (±1 A maximum peak current) by the built-in totem-pole gate pre-
driver circuit
Can operate in synchronization with an external pulse signal, or with another controller IC
Pulse-by-pulse overcurrent limiting (OCL)
Intermittent operation under continuous overcurrent
Low quiescent current drain when shut off by grounding the ON/OFF pin
HA16114: IOFF = 10 µA (max)
HA16120: IOFF = 150 µA (max)
Externally trimmable reference voltage (Vref): ±0.2 V
Externally adjustable undervoltage lockout points (with respect to VIN)
Stable oscillator frequency
Soft start and quick shut function
Note: The reference voltage 2.5 V is under the condition of VIN 4.5 V.
