Texas Instruments TPS3897ADRYR | Demoboard DRV5825PEVM-AMPS097
4.5-V to 26.4-V, 7.5-A stereo, 15-A mono, Piezo driver with smart I/V protection evaluation module
Overview
| Topology | Class D Audio Amplifier |
Description
The TPS3897ADRYR is a very small supervisory circuit that monitor voltages greater than 500 mV with a 0.25% (typical) threshold accuracy and offer adjustable delay time using external capacitors. The TPS3897ADRYR also has a logic enable pin (ENABLE or ENABLE) to power on and off the output. With the TPS3895, for example, when the input voltage pin (SENSE) rises above the threshold, and the ENABLE pin is high, then the output pin (SENSE_OUT) goes high after the capacitor-adjustable delay time. When SENSE falls below the threshold or ENABLE is low, then SENSE_OUT goes low.
Features
- Very Small USON (1.45 mm × 1.00 mm) Package
- Adjustable Threshold Down to 500 mV
- Threshold Accuracy: 1% Over Temperature
- Capacitor-Adjustable Delay Time
- Low Quiescent Current: 6 µA (Typical)
- External Enable Input
- Open-Drain (Rated at 18 V) and Push-Pull Output
- Temperature Range: –40°C to 125°C
- Pin-for-Pin Compatible With MAX6895/6/7/8
Typical applications
- Nolebook and Desktop Computers
- Portable, PDAs and Handheld Products
- Battery-Powered Products
- DSPs, Microcontrollens, and Microprocessors, FPGAs and ASICs
