Texas Instruments TLV1805-Q1 | Demoboard PMP21953

40V, Rail-to-Rail Input, Push-Pull Output, High Voltage Comparator with Shutdown

Overview

TopologyHalf-Bridge Converter symmetrical isolated
Input voltage8-36 V
Output 118 V / 0.05 A
IC revisionA

Description

This reference design demonstrates a cost focused approach of an isolated power supplies with low current capability. The design consists of three designs of three different topologies. All three design options are based on a high voltage comparator TLV1805-Q1 which works as a free-running oscillator and a driver. All three are unregulated, and the ouptut voltage directly depends on the input voltage.

Features

  • 3.3 V to 40 V Supply Range
  • Low Quiescent Current: 135 μA
  • High Peak Current Push-Pull Output
  • Rail-to-Rail Inputs with Phase Reversal Protection
  • Built-In Hysteresis: 14mV
  • 250ns Propagation Delay
  • Low Input Offset Voltage: 500 μV
  • Shutdown with High-Z Output
  • Power-On Reset (POR)
  • SOT-23-6 Package

Typical applications

  • OR-ing MOSFET Controller / MOSFET Gate Driver
  • Reverse Current Protection Smart Diode Controller / Overvoltage, Undervoltage, and Overcurrent Detection
  • High Voltage Oscillators / PLC
  • System Monitoring for Infotainment & Cluster
