描述 Description

The HV53001 device is an integrated driver solution for various applications, which consists of three main functional blocks (1) High voltage driver, (2) SPI interface and (3) DC/DC boost controller with power MOSFET.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 24mA. Each high voltage output is capable of driving up to 250 pF capacitive 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.The SPI interface is used to communicate between the host processor and the high voltage drivers. This interface accepts a 3.3V logic I/O signal up to clock speed of 32MHz. 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.This IC also includes an integrated DC/DC controller with power MOSFET. The controller is used in a flyback 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 supplies referenced to the ±135V supply rails.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.A proper 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 control the power supplies to power up or down the high voltage driver. It is used in conjunction with the external high voltage FET transistors.Few safety features are added to the DC/DC converter. The over-voltage protection monitors both high voltage rails to protect the driver against over-voltage condition. A short circuit protection detects any short circuit event at the high voltage rails by monitoring the current flow through the power FET transistor. When a short circuit is detected, the DC/DC controller will shut down the converter and send a fault signal at the SHORT pin.A over-temperature monitor function is also added in the converter IC. It sends a fault signal at the TEMP pin when it detects the temperature over the threshold temperature. The HV53001 device is packaged in a 9x9mm 105 balls TFBGA package. All high voltage I/O are arranged to have sufficient clearance for safety.Microchip has partnered with Tanvas to create this chipset that optimizes size and features for enabling surface haptic applications. Learn more >>

简介

HV53001属于集成电路（IC）的移位寄存器。由制造生产的HV53001移位寄存器移位寄存器是低级逻辑器件，通常用于在串行和并行方式之间转换数字逻辑信号形式的数据，或在数字字内移动数据位的位置。移位寄存器通常使用集成到一个设备中的一组触发器来实现，常用于集成度更高的逻辑器件，但仍可用于 I/O 扩展等应用，在这些应用中离散形式的函数可能会非常有用。
