MAX77501

110V

High-Efficiency Piezo Haptic

Actuator Boost Driver

PK-PK

General Description

Benefits and Features

The MAX77501 is a high-efficiency controller driver for

piezo haptic actuators and is optimized for driving up to

2µF piezo elements. It can generate a single-ended haptic

● 110V

Haptic Waveforms Generation

PK-PK

● Optimized for up to 2µF Haptic Piezo Actuator

● 2.8V to 5.5V Input Supply Range

waveform of up to 110V

amplitude from a 2.8V to

● 600μs Start-Up Time to Haptic Playback

PK-PK

5.5V input power supply or a single cell Li+ battery. Mem-

ory playback and haptic waveforms real-time streaming

modes are supported.

● High-Efficiency, Low I Extends Battery Life

• 75μA Standby Current/1μA Shutdown Current

• Maxim Patented Ultra-Low Power Boost

Architecture

A 25MHz SPI interface provides full system access and

control, including fault reporting and monitoring. This al-

lows for a rapid 600µs playback start-up time from shut-

down. The on-board memory can be dynamically allocated

as multiple waveforms storage or as a FIFO buffer. The

IC also implements an ultra-low power boost architecture

providing the lowest power consumption solution for a

haptic actuator driver.

● 12-Bit Haptic Waveform Playback DAC

● Real-Time Streaming and RAM Playback Modes

• 9k FIFO Buffer with FIFO Ready Status Signal

• 8k RAM Buffer for Waveforms Storage

● 25MHz SPI Interface

• SPI Ready, Warning and Fault Conditions Interrupt

● Protection Features

Built-in undervoltage lockout (UVLO), cycle-by-cycle over-

current limit, overvoltage and thermal shutdown protec-

tions ensure safe operation under abnormal operating

conditions.

• Programmable Cycle-by-Cycle Overcurrent Limit,

130V Overvoltage, UVLO, and Thermal Protections

● Small Size and Low Profile

• 2.42mm x 2.02mm, 30 Bump WLP

The MAX77501 is available in a 30-bump, 0.4mm pitch,

wafer-level package (WLP).
