LT1510-5IGN

Constant voltage/constant current charger

peculiarity

  • Charge nickel-cadmium, nickel-metal hydride batteries and lithium-ion batteries - only one 1/10W resistor programming required charging current
  • High efficiency 1.5A internal switch and sense resistor current mode PWM
  • 3% typical charge current accuracy
  • 0.5% precision voltage reference mode charge or overvoltageprotection
  • Current sensing is available at the terminals of both batteries
  • Low reverse battery leakage current: 3μA
  • Soft start of the charging current
  • Shutdown control
  • The 500kHz version uses a small inductor

description

随着开关频率高达500kHz的，在LT ® 1510电流模式PWM电池充电器是最小，最简单，最有效的解决方案向现代快速充电，包括锂离子（锂离子电池）可充电电池，镍金属氢化物（镍氢电池*）和镍镉（NiCd）*需要恒定电流和/或恒压充电。 An internal switch capable of delivering 1.5A DC (2A peak current). The built-in current sense resistor of 0.1 ohms makes it easy to program the charge current. A resistor (or programming current from the DAC) is the charge current (1.5A) set within 5% of the accuracy requirement. The LT1510 meets critical constant voltage rechargeable lithium battery requirements with 0.5% reference voltage accuracy. The LT1510 can be charged from a 2V to 20V battery. Current ground detection is not necessary and can be directly connected to the negative ground of the battery. The saturation switch operates at 200kHz (LT1510-5 at 500kHz) for high charging efficiency and small inductor size. There is no need to block between the diode chip and the battery, because the chip goes into sleep mode when the wall adapter is unplugged by only 3μA. Soft start and shutdown capabilities are also provided. The LT1510 is thermally resistive in a 16-pin fusion resulting power SO package with a 50°C/W, 8-lead SO and 16-pin PDIP.
