OB3362FRP is Marking OB3362RP.

Description

The OB3362RP is High Performance LED Driver

The OB3362F is a highly integrated and high performance LED driver that optimized for LCD backlight application. It integrates a boost driver and 4 channels of current balancer that optimized to drives multi LED arrays, and thus provides a high performance LED backlight solution with minimized BOM count.

The OB3362F contains a PWM boost driver which uses current mode control and fixed frequency operation. The operation frequency can be programmed by setting external resistor value at RI pin.

The OB3362F integrates 4 channels current balancer with up to 200mA current capability per channel and it can achieve 3% matching accuracy among LED strings. The minimum voltage of current source is regulated to as lower as 350mV, which benefits the efficiency and improves the IC thermal performance.

The OB3362 supports external PWM dimming and internal burst dimming mode which allow flexible control of the backlight luminance. The LED current is directly modulated by external PWM duty cycle when PWM dimming mode is selected. The LED current can be adjusted by an external DC voltage when internal burst dimming mode is selected.

DRV8833C datasheet

 

Description

The DRV8833C provides a dual-bridge motor driver solution for toys, printers, and other mechatronic applications.

The device has two H-bridges and can drive two DC brushed motors, a bipolar stepper motor, solenoids, or other inductive loads.

Each H-bridge output consists of a pair of N-channel and P-channel MOSFETs, with circuitry that regulates the winding current. With proper PCB design, each H-bridge of the DRV8833C can drive up to 700-mA RMS (or DC) continuously, at 25°C with a VM supply of 5 V. The device can support peak currents of up to 1 A per bridge. Current capability is reduced slightly at lower VM voltages.

Features

1. Dual H-Bridge Motor Driver With Current Control
(1) 1 or 2 DC Motors or 1 Stepper Motor
(2)Low On-Resistance: HS + LS = 1735 mΩ (Typical, 25°C)

2. Output Current Capability (at VM = 5 V, 25°C)
(1) PWP (HTSSOP) Package
A. 0.7-A RMS, 1-A Peak per H-Bridge
B. 1.4-A RMS in Parallel Mode

3. RTE (QFN) Package
(1) 0.6-A RMS, 1-A Peak per H-Bridge
(2) 1.2-A RMS in Parallel Mode

Applications:

1. Point-of-Sale Printers

2. Video Security Cameras

3. Office Automation Machines
