TPB7462 4s High Accuracy Secondary Hardware Protector With CTL and LDO Features Applications  Maximum Voltage Input 28V  Notebook  Wide Operation Voltage Range from 4V to 24V  Portable Equipment  Low Current Consumption Description − Normal Mode 4μA at +25°C − Shutdown Mode 0.4μA at +25°C  High Accuracy Voltage Detection Circuit for each cell − Programmable Overcharge Threshold Voltage from 4.1V to 4.8V in 50mV step − Overcharge Threshold Accuracy ±20mV (+25°C) − Overcharge Threshold Accuracy ±25mV (10°C to +60°C) − Overcharge Hysteresis Voltage −380mV  Internal Delay Timer for Overcharge − Selectable Overcharge Detection Delay Time 2s, 4s, 6s, and 8s The TPB7462 series is a secondary overcharge hardware protector for 2s, 3s, or 4s lithium-ion battery packs TPB7462 series provides high accuracy overcharge threshold to avoid the safety risk from battery pack. It also provides the CTL pin to directly control output or connect PTC (Positive Temperature Coefficient) resistor to monitor overtemperature of battery pack. The TPB7462 integrates a LDO for powering external circuit with extremely low leakage current. TPB7462 is available in WDFN2x2-8 package. Its operation temperature range is from −40°C to +85°C. − Selectable Delay Time for Shutdown 2s, 4s, 6s, and 8s  High CO Pull Up Voltage − Selectable CMOS Active High or Low output  Test Mode to Shorten Mass Production Time  Integrated Linear Regulator − Selectable LDO Output 3.0V, and 3.3V − LDO output Cut off Voltage 2.5V − Output Current 2mA − Short Circuit Protector Typical Application Circuit www.3peakic.com.cn 1 / 15 Rev.A.1 PDF
