Dual H-Bridge Driver with Boost Converter
GENERALDESCRIPTION
■ PACKAGE OUTLINE
The NJW4814 is a dual H-bridge driver with boost converter IC.
It can boost the output voltage from Li-ion battery and/or a 5V power
supply and drives a piezo device by two H- bridge drivers.
48ms of internal fixed soft start function of the boost circuit sets a limit
to startup current.
NJW4814MLE
The dual H-bridge drivers have independent signal inputs and a fault
output function, therefore the NJW4814 improves controllability from a
microcomputer.
The input frequency of H-bridge driver is up to 300kHz.

PIN NAME
FUNCTION
Power Supply pin for H-Bridge driver block.
NUMBER
16
Insert a bypass capacitor close to the VDD_HB pin – the GND pin connection in
order to lower high frequency impedance.
VDD_HB
Overvoltage detection pin of SW.REG.
When it detected overvoltage, the VOVP pin sinks a current and discharges the
output voltage.
VOVP pin should be connected to VDD_HB pin.
Output pin of H-Bridge driver Bch (one side).
The function is same as 12pin.

PGND
The RADJ pin becomes the high impedance at standby.
It prevents a current flowing into the output voltage setting resistor.
Feedback Setting pin

H Bridge Driver Block Over Current Protection
The overcurrent protection function operates when the high side SW current flows more than IDCTH or the low side SW
current flows more than IDCTL. The overcurrent protection operates in three steps.
(1) Sensing step
·Turn off power MOSFETof the switching regulator
·Turn off power MOSFETof the H-bridge driver
·Reset a soft start
·Reset an FB pin voltage
·Connect a dummy road between VOVP pin-GND pin
(2) Output stop step
After the overcurrent detection, 500 ms (typ.) continues an output stop.
(3) Return step
After an output stop, the soft start operates. Then the IC operation shifts to normal operation.
