Overview
The TPT29539AQ is a 16-bit GPIO expander with interrupt and weak pull-up resistors for I2C-bus applications. The power supplier voltage ranges from 1.65 V to 5.5 V, allowing for the TPT29539AQ to interconnect with 1.8 V microcontrollers.
The TPT29539AQ contains 16-bit Input and Output. The open-drain interrupt ( INT ) output is changeable when any input state changes from its related register state. The device is used to indicate the system master that an input state has changed. INT can be connected to the interrupt input of a microcontroller. The TPT29539AQ can remain a simple slave device. The power-on reset sets the registers to their default values and initializes the device state machine. The TPT29539AQ also has a hardware RESET pin to reset the device to its default state.
All input/output pins do not have internal pull-up resistors, thus the device can save power consumption as communicating with external I/Os. Two hardware pins (A0, A1) select the fixed I2C-bus address and allow up to four devices to share the same I2C-bus.
The TPT29539AQ is available in the TSSOP24 package, and is characterized from −40°C to +125°C to meet automotive application requirements.
