SG1548 Datasheet
Key Features: • Monitors four DC voltages and the AC line • Precision 2.5V ±1% low-drift reference • Fault tolerance adjustable from ±5% to ±40% • ±3% trip threshold tolerance over temperature • Separate 10mA, 40V overvoltage, undervoltage and AC line fault outputs • Fault delay programmable with a single capacitor • 30mV comparator hysteresis to prevent oscilla-tions • On-chip inverting op amp for negative voltage • Open-collector output logic or expandability • Operation from 4.5V to 40V supply The SG1548 is an integrated circuit capable of monitoring up to four positive DC supply voltages simultaneously for overvoltage and undervoltage fault conditions. An on-chip inverting op amp also allows monitoring one negative DC voltage. The fault tolerance window is accurately programmable from ±5% to ±40% using a simple divider network on the 2.5V reference. A single external capacitor sets the fault indication delay, eliminating false outputs due to switching noise, logic transition current spikes, and short-term AC line interrup-tions. An additional comparator referenced to 2.5V allows the AC line to be monitored for undervoltage conditions or for generation of a line clock. The comparator can also be used for programmable undervoltage lockout in a switching power supply. Uncommitted collector and emitter outputs permit both inverting and non-inverting operation. External availability of the precision 2.5V reference and open-collector logic outputs permit expansion to monitor additional voltage using available open-collector quad comparators.

Key Features:
• Source or sink 5A peak
• Half-bridge with internal diodes
• TTL input compatibility
• Either dual- or tri-state output
• Direct PWM motor drive from microprocessor
• Built-in thermal protection
• SG3635P replaces UDN2935Z
The SG1635 is a monolithic integrated circuit designed to interface low-level logic signals with high-current, inductive, or capacitive loads. This device is particularly adept at high-speed pulse width modulation for motor drives or Class D audio amplifiers, and when used in pairs, they can provide full bridge drive for bi-directional control.
With TTL-compatible units, this device will either source or sink up to 5A of peak current with interlock protection to insure that source and sink cannot be on simultaneously. Additional protection is provided by thermal shutdown of the source output if the chip temperature rises above 160°C. High speed internal commutating diodes are also included.

The circuit contains a triangle waveform oscillator, a wideband operational amplifier for error voltage generation, a summing/scaling network for level-shifting the triangle waveform, externally programmable PWM comparators and dual ±100mA, ±22V totem pole drivers with commutation diodes for full bridge output. A SHUTDOWN terminal forces the drivers into a floating high-impedance state when driven LOW. Supply voltage to the control circuitry and to the output drivers may be from either dual positive and negative supplies, or single-ended.
