Description
PBL 3770A is a bipolar monolithic circuit intended to control and drive the current in one winding of a stepper motor. It is a high power version of PBL 3717 and special care has been taken to optimize the power handling capability without suffering in reliability.
The circuit consists of a LS-TTL compatible logic input stage, a current sensor, a monostable multivibrator and a high power H-bridge output stage. The circuit is pin-compatible with the PBL 3717 industry-standard driver.
Two PBL 3770A and a small number of external components form a complete control and drive unit for LS-TTL or microprocessor-controlled stepper motor systems.

Key Features
• Half-step and full-step operation.
• Switched mode bipolar constant current drive
• Wide range of current control 5 -1800 mA.
• Wide voltage range 10 - 45 V.
• Designed for unstabilized moto supply voltage.
• Current levels can be selected in steps or varied continuously.
• Thermal overload protection.

Description
The CPC1580 optical gate driver provides isolated control of a discrete power MOSFET transistor without the need of an external power supply.
Control of the power MOSFET transistor is accomplished by the application of sufficient input LED current to activate the driver circuitry.
On the load side, an external storage capacitor and an internal bootstrap diode enable the internal photovoltaic and gate driver circuitry to provide fast output switching characteristics by supplying the charge necessary to satisfy the MOSFET’s bias requirements.
Provided in a small 8-pin package, the CPC1580 provides 3750Vrms of input-to-output isolation.

Features
• Drives External Power MOSFET
• Low LED Current (2.5mA)
• Requires No External Power Supply
• Load Voltages up to 65V
• High Reliability
• Small 8-pin Surface Mount Package
• 3750Vrms Input/Output Isolation

Applications
• Industrial Controls
• Instrumentation
• Medical Equipment Isolation
• Electronic Switching
• I/O Subsystems
• Appliances

San Jose, California – January 8, 2008 – Fairchild Semiconductor (NYSE: FCS) introduces the industry’s most integrated CCFL backlight inverter drive ICs providing space and cost savings, superior system reliability and simplified design for N-N half-bridge, push-pull, and P-N full-bridge LCD backlight inverter designs. The FAN7316 and FAN7317, featuring a wide input voltage range, and built-in open lamp protection (OLP) and open lamp regulation (OLR*) circuit, eliminate up to 30 external components in four lamp circuit inverter designs compared to similar devices on the market. These highly integrated CCFL backlight inverter drive ICs also feature selectable dimming polarity and analog and burst dimming functions, which simplify design and speed time-to-market.

“Fairchild’s FAN7316 and FAN7317 offer the industry’s most comprehensive protection functions resulting in superior system reliability. By reducing the number of components, these devices specifically address the ever-growing need to reduce overall system cost in LCD designs,” said Jay Lee, director of Fairchild’s Lighting product line.

Industry-leading benefits of the FAN7316 and FAN7317 include:

  • Space and cost savings – eliminating the need for external IC _VCC regulation circuitry and OLP and OLR* detection circuitry and P-MOSFET driving circuitry* with its wide input voltage range ( FAN7316: 4.5V to 24V, FAN7317 : 6V to 25.5V) and built-in OLP and OLR* detection circuitry. This eliminates up to 30 external components.
  • System reliability – offering the industry’s most comprehensive protection functions including built-in OLP circuit, open lamp regulation (OLR), short circuit protection (SCP), thermal shutdown (TSD), soft-start and arc protection.
  • Design flexibility – featuring a wide input voltage range, selectable dimming polarity, analog and burst dimming mode and PWM dimming by an external pulse signal, the FAN7316 and FAN7317 offer flexibility in designing N-N half-bridge, push-pull and P-N full-bridge LCD backlight inverters.
Fairchild offers a comprehensive CCFL backlight inverter portfolio including Buck-Royer, push-pull, half and full-bridge topologies complemented by Fairchild’s single and dual MOSFETs.

* FAN7317 only

The FAN7316 and FAN7317 are available in a 20 pin SOIC lead (Pb)-free package that meets or exceeds the requirements of the joint IPC/JEDEC standard J-STD-020C. Both utilize lead-free (Pb-free) terminals and have been characterized for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/JEDEC standard J-STD-020. All of Fairchild's products are designed to meet the requirements of the European Union's Directive on the restriction of the use of certain substances (RoHS).

Price (each, 1000 pcs.): US$ 1.48 for the FAN7316
US $1.55 for the FAN7317
Availability: Now 

Delivery: 12 weeks ARO
