HV53001
16-Channel, ±135V Push-Pull Driver with RTZ,
Current Sensor and Built-in Boost Converter
Features
General Description
• 16-Channel Push-Pull Output
The HV53001 device is an integrated driver solution
for various applications, which consists of three main
functional blocks (1) high-voltage driver, (2) SPI inter-
face and (3) DC/DC boost controller with power
MOSFET.
• Return-To-Zero (RTZ) and High-Impedance (Hi-Z)
Function
• Up to ±135V Output Voltage
• 24 mA Minimum Source Sink Output Current
• 250 pF Maximum Output Load
• Current Sensor Output
The high-voltage driver block includes 16 push-pull
drivers capable of ±135V output swing with Return-To-
Zero (RTZ) function. Each output driver is capable of
sourcing and sinking at least 24 mA. Each high-volt-
age output is capable of driving up to 250 pF capaci-
tive load. A global current sensor function is also
integrated into this device to monitor the charge and
discharge currents. The measured current is mapped
to a low-voltage analog output with a scale factor of
3.1 V/V via a current sensing resistor.
• SPI Interface with Quad-Latched 2-bit per Chan-
nel Architecture
• Power-on Reset Function
• DC/DC Boost Converter with Power MOSFET
• 2.7 to 5.5V Converter Input Voltage
• Short Circuit Protection
• Overtemperature Monitor
The SPI interface is used to communicate between the
host processor and the high-voltage drivers. This inter-
face accepts a 3.3V logic I/O signal up to clock speed
of 32 MHz. Five digital LATCH control signals manage
the data flow and the firing pattern. It establishes the
output to one of four possible states: VPP, VNN, 0V or
high impedance.
• Power ON/OFF Sequence Control
• Shutdown Function
• 105-ball 9 x 9 mm TFBGA Package
Application
• Surface Haptic Application
• MEMS Driver
This IC also includes an integrated DC/DC controller
with power MOSFET. The controller is used in a fly-
back configuration to generate four high-voltage rails,
±135V and ±123V, for the high-voltage driver block.
The ±123V rails are created from two 12V floating sup-
plies referenced to the ±135V supply rails.
• Piezo Driver
The converter accepts input voltage from a single
2.7V-5.5V input voltage rail. A built-in positive charge
pump and a simple external negative charge pump
convert the input supply to +6.5V and -6.0V supplies to
power the high-voltage driver block.
Aproper power on and off sequence is critical to ensure
the operation of the high-voltage driver. A power
sequence control circuit is included for the user to con-
trol the power supplies to power up or down the high-
voltage driver. It is used in conjunction with the external
high-voltage FET transistors.
Safety features are added to the DC/DC converter. The
overvoltage protection monitors both high-voltage rails
to protect the driver against an overvoltage condition.
Short circuit protection detects any short circuit event at
the high-voltage rails by monitoring the current flow
