Circuit Description
Input Circuit
control inputs IH1,2 consist TTL/CMOS compatible Schmitt-Triggers with hysteresis. Buffer amplifiers driven these stages convert logic signal into necessary form driving power output stages. inputs protected clamp-diodes. inputs connected internal gate-driving units N-channel vertical power-MOS-FETs.
Output Stages
output stages consist RDSON Power-MOS H-bridge. H-bridge configuration, D-MOS body diodes used freewheeling when communicating inductive loads. high-side switches used single switches, positive negative voltage spikes which occur when driving inductive loads limited integrated power clamp diodes.
Short Circuit Protection
outputs protected against output short circuit ground output short circuit supply voltage, overload (load short circuit). internal OP-Amp controls Drain-Source-Voltage comparing DS-Voltage-Drop with internal reference voltage. Above this trip point OP-Amp reduces output current depending junction temperature drop voltage.
Overtemperature Protection
high-side low-side switches also incorporate over temperature protection circuit with hysteresis which switches output transistors. case high-side switches, status output low.
Undervoltage Lockout
When reaches switch-on voltage VUVON becomes active with hysteresis. High-Side output transistors switched supply voltage drops below switch value VUVOFF.
Open Load Detection
open load detection BTM7751G works condition based voltage measurement source high side switch. order open load detection connected pull resistor. Because this pull resistor would connect bridge output supply needs disconnected whenever high side switch This done transistor shown application example (Figure "Application Example BTM7751G" Page 15). check open load: (both high side switches off) LOW, HIGH (only side switch Connect (open load pull transistor
load connected properly will pull down voltage value close load disconnected resistor will pull voltage value close Vcc. voltage higher than open load detection voltage VOUT(OL) then will pulled down.
