r Undement p lo e Dev Saves power during standby, enhances efficiency MIP2C2 High-Performance IPD for Battery Chargers Unit : mm .10 +0 0.25 -0.05 ■ Overview MIP2C2 is a high-performance IPD designed for 7W battery chargers. It features built-in protection circuits necessary for compact power source charger circuitry. This allows a significant reduction in externally connected parts. MIP2C2 provides PWM control when a normal load is applied and intermittent control with low load. This results in greater efficiency for very low to maximum loads, while also conserving power during standby. 9.4±0.3 1 2 5 4 0.6+0.25 -0.01 0.5±0.1 ● Built-in charge protection circuit Built-in overcurrent, overheating, load shorting and overvoltage protection circuits ● Significantly reduced power consumption with no load* 20mW at 100VAC, 25mW at 240VAC ● High efficiency with rated load* 75% at 100VAC,72% at 240VAC ● Reduced number of parts (12 less than conventional Panasonic models) * With worldwide input and 5.8V/0.7A output 3˚ to 15˚ 3 2.54±0.25 3.4±0.3 3.8±0.25 ■ Features 7.62±0.25 7 6.3±0.2 8 0.4±0.1 1.2±0.25 0.6±0.1 (1,4,5,8PIN) (2,3,7PIN) DIP8-A1(CF) ■ Applications ● Chargers (for cellular phones, etc. ) ■ Block Diagram ■ Pin Descriptions Pin No. Function DRAIN VCC VCC UV Reg. 1 VDD 2 FB 3 CL 4 VCC 5 Drain 6 7 Source 8 Source 12V 10V VDD VCC OVP 5.7V 22V Overheat protection Oscillator Restart trigger S Q R Q S Q R Q VDD UV CL Max Duty Clock Clamp voltage variable circuit (10 to100%) 15% 20% 5.7V 4.7V Gate driver Power MOSFET Blanking pulse circuit Low load detection Intermittent control FB Drain current detection SOURCE ¶ The products and specifications are subject to change without any notice.
